Dental Implants
Dental implants are artificial tooth roots used to support a restoration for a missing tooth or teeth, helping to stop or prevent jaw bone loss. The dental implant procedure is categorized as a form of prosthetic (artificial replacement) dentistry, but also is considered a form of cosmetic dentistry.
People who have lost teeth might feel too self-conscious to smile or talk. Additionally, biting irregularities caused by tooth loss can have a negative effect on eating habits, leading to secondary health problems like malnutrition.
By replacing missing tooth roots, dental implants provide people with the strength and stability required to eat all the foods they love, without struggling to chew. Additionally, dental implants stimulate and maintain jaw bone, preventing bone loss and helping to maintain facial features
Why should you use dental implants for replacing missing teeth?
- Bone loss is stopped when implants are placed.
- Sacrificing the adjacent teeth by cutting them down to be used as abutments for a bridge becomes obsolete.
- It is a predictable treatment: Success rates (86%-98.5%) vary depending on the general health of the patient and on the quality of bone.
- Decay cannot destroy them.
- They are biocompatible: bone cells can grow on the implant surface, as the body does not recognize titanium as a foreign body.
- Implants can be used to stabilize dentures thus preventing their movement that is embarrassing and painful.
In expert hands, dental implants have better prognosis than bridgework as they re-create the natural physiologic loading of the jawbone, which is imperative for its maintenance.
Placements of dental implants are for most people a painless operation. Depending on the number of implants that are placed in one visit, the patient is expected to be able to go to work in 1 or 2 days.
Implants can improve facial appearance, the digestion and the quality of life.
Dental Implants: Consultation, Placement, and Recovery
To determine if implants are right for you, a consultation with your dentist, oral surgeon, and/or periodontist or prosthodontist is needed. During this appointment, your dental professional will thoroughly examine your teeth and gums and evaluate bone density and quantity. This may involve X-rays and computer tomography scans (CT scans) to ensure there is sufficient bone structure for placing the implant(s), and to determine exactly where the implant should be placed.
Based on the condition of your oral tissues, oral hygiene and personal habits, and commitment to follow aftercare instructions, your dentist will advise you of the most appropriate dental implant treatment plan.
Single Tooth Dental Implants
If you are missing a single tooth, an implant can replace it. A dental implant replaces both the lost natural tooth and its root.
What are the advantages of a single-tooth implant
A dental implant provides several advantages over other tooth replacement options. In addition to looking and functioning like a natural tooth, a dental implant replaces a single tooth without sacrificing the health of neighboring teeth.
Because a dental implant will replace your tooth root, the bone is better preserved. Dental implants integrate with your jawbone, helping to keep the bone healthy and intact. In the long term, a single implant can be more esthetic and easier to keep clean.
How will the implant be placed?
First, the implant, which looks like a screw or cylinder, is placed into your jaw. Over the next three to six months, the implant and the bone are allowed to bond together to form an anchor for your artificial tooth. During this time, a temporary tooth replacement option can be worn over the implant site.
Finally, a replacement tooth called a crown will be created for you by your dentist and attached to the abutment. After a short time, you will experience restored confidence in your smile and your ability to chew and speak. Dental implants are so natural-looking and feeling; you may forget you ever lost a tooth.
Remplacement plusieurs dents
Avantages des prothèses fixes sur implants :
Dans ce cas, afin de remplacer trois dents manquantes dans la partie arrière de la bouche, une prothèse partielle fixe sur implants demeure la seule alternative fixe. Les prothèses traditionnelles ne peuvent offrir autant de stabilité et un fonctionnement aussi normal.
Des implants, posés en remplacement de vos dents arrière perdues, donneront à votre dentition une résistance et une stabilité nouvelles et incomparables, qui vous permettront de manger tout ce dont vous avez envie. Cela vous permettra aussi de conserver l’intégrité de votre mâchoire et de votre apparence.
- La seule solution fixe à cette condition.
- Une solution stable et solide, qui vous permet de manger tout ce dont vous avez envie.
- Préserve l’apparence faciale et prévient la perte osseuse.
Traitement:
Suite à l’examen initial, vous devez vous attendre à 4 ou 5 visites additionnelles avant que la prothèse finale soit fixée de manière permanente. Il est normal d’avoir quelques ecchymoses et un peu d’enflure au niveau des gencives et des tissus mous suite à l’intervention. L’inconfort est habituellement traité à l’aide d’analgésiques courants. En général, vous pouvez retourner au travail le jour suivant.
Déroulement du traitement
Le traitement décrit ici représente une des nombreuses options disponibles. Consultez votre dentiste afin qu’il vous conseille la solution la mieux adaptée à votre condition spécifique.
Mise en place du pont fixe – étape par étape
1. Avant l’intervention
Il manque trois dents à l’arrière de la mâchoire et la seule solution valable pour remplacer ces dents est d’installer un pont fixe. Le pont est formé de toutes les dents, en une seule pièce, et est fixé sur des implants dentaires.
2. Pose des implants
Les implants sont posés en premier, généralement au cours d’une seule séance. Un pont temporaire peut être mis en place au même moment, vous permettant de fonctionner normalement presque immédiatement après avoir quitté le cabinet du dentiste.
3. Fixation du pont
Les implants doivent avoir le temps de s’intégrer à l’os de la mâchoire avant de pouvoir y fixer le pont permanent, ce qui représente un délai d’environ 3 mois après la mise en place. Par contre ce délai peut varier selon les dents atteintes et les exigences esthétiques.
4. Résultat final
Le nouveau pont, vous jouirez alors d’une solution stable et solide, qui vous permettra de manger tout ce dont vous avez envie.
Replacing all teeth
Total edentulous
Dental Implants - Replacing all teeth
In case of total tooth loss a fixed prosthesiswith porcelain teeth on dental implants is the ideal solution.
Before the introduction of dental implants, there were no fixed solutions available for people totallyedentulous. Nowadays, it is possible to completely redo the teeth of a jaw with dental implants and a fixed prosthesis, resulting in a permanent, stable and aesthetically pleasing solution.
- Can eat and work like natural teeth.
- Offers a solution for life, and sturdy.
- Preserves the facial appearance and prevents bone loss.
Course of treatment
The course of treatment and the number of visits is largely dependent on specific conditions. But on average from 8 to 10 visits should be sufficient for the installation of a fixed prosthesis. Most patients report that they feel much more comfortable following the procedure than they had anticipated.
Installation of fixed prosthesis - step by step
The treatment described here is one of many options available. Consult your dentist to advise you that the best solution for your specific condition.
1.Before the intervention
The dentist determines what needs to be done, getting ready, and prepare the patient for the procedure to come.
2.Implant placement
The first step is to place dental implants to replace the roots of missing teeth. In this case, multiple implants are used. Temporary teeth are attached to allow you to eat and function normally until the permanent prosthesis is installed.
3.Prosthesis installation
The permanent prosthesis with porcelain teeth is secured to the upper part of the implants. It may take 2 to 3 views before we finally secure the prosthesis.
4.Final Result
It should be very difficult to differentiate your new teeth to natural teeth, and, for you and for others. People who have had traditional dentures before a fixed prosthesis often report that this is an exciting and extremely positive experience.
Removable denture anchored on implants (acrylic teeth)
One of the alternatives to fixed prosthesis is to install a removable overdenture with acrylic teeth, which is anchored on implants. It is best, whenever possible, to avoid the traditional denture because it has many disadvantages.
Removable denture anchored on implants (acrylic teeth)
A removable denture which is connected by means of attachments, ball anchors or bars, which are attached to two or more implants in the front of the jaw.
The implants help keep the denture in place, while allowing better chewing function and offering more comfort. The cost is usually what motivates the choice of a removable rather than a fixed prosthesis, but the results are not comparable.
Removable denture
The denture is simply placed on the gums and tooth loss mask. This option does not offer any significant advantage, with the exception of its low cost and its easy installation.
The disadvantages are many: discomfort during feeding, low aesthetic quality, modification of language and sensitivity of the gums caused by the movement of the prosthesis. Moreover, a full denture placed in the upper night to taste significantly jaw.
The Immediate Function All-on-4
The Immediate Function All-on-4 procedure is an Immediate Function procedure for people with dentures or people in need of full upper and/or lower restorations. With the All-on-4 procedure, after initial work-up, qualified patients receive just four implants and a full set of new replacement teeth in just one appointment - without bone grafts.
Forqualified patients, we can deliver the All-on-4 procedure for restoring a full arch of upper and/or lower teeth. Unlike other approaches that use six, eight, or more implants and often involve bone grafting, we use a proven technique that involves only four specially placed implants.
Not only oes this procedure save time and money, but it's a safer and smarter alternative to dentures: no deterioration or shrinkage of the jaw, no pain or discomfort, no loss of chewing ability, and no unnecessary facial aging.
A Detailed Look
At Dr.Morneault, Voisine, Michaud dental center in collaborations with Dr. René Caissie and Nobel Biocare we deliver the full benefits of the Immediate Function All-on-4. Here is a closer look at the procedure courtesy of Nobel Biocare.
Immediate fonction™
Functional and esthetic teeth in one treatment session
Immediate Function™ is a core concept of Beautiful Teeth Now™.
The benefits of Immediate Function™ are:
- Shortened treatment time – it is possible to go from tooth loss to having functional and esthetic teeth in one treatment session.
- Better clinical efficiency.
- Greater patient comfort.
Immediate Function - Bone
Left: Bone within the pores of TiUnite®.
Right: Cell extension of an osteoblast (bone-producing cell) anchored in a pore of TiUnite®.
Immediate Function - Unique TiUnite
TiUnite® allows bone to grow by osseoconduction along the implant surface (left) whereas bone formation on a machined implant surface (right) is characterised by bone apposition towards the surface.
Immediate Function - Increased Stability
Left: The groove at the thread flank takes the TiUnite® implants to a new level of effectiveness.
Right: Bone forms more rapidly within the groove than on surfaces without the groove, resulting in faster osseointegration and increased implant stability.
Immediate Function - Extending
Left: Bone within the groove of a TiUnite® implant.
This is achieved through the unique properties of our biomaterial TiUnite® in combination with Groovy, which means no healing time is required prior to functioning.
TiUnite® is a highly crystalline and phosphorous enriched titanium oxide. It presents a microstructure without sharp features characterized by the presence of uniformly distributed open pores in the low micrometer range. This surface is proven to interact with the biological environment and promote tissue integration.
TiUnite® attracts bone-producing cells, allowing them to proliferate and form bone directly on the surface by osseoconduction. The result is a faster rate of osseointegration, and a remarkable ability to maintain the implant stability at a high level throughout healing.
Increased stability with grooves
Adding grooves along the threaded portion of the implant brings a new dimension to our TiUnite® implants.
The size of the groove is intermediate to the micro structured TiUnite® surface and the macro design of the implant. The optimally dimensioned groove, together with the TiUnite® surface, creates a favorable environment for preferential and faster bone formation within and along the groove.
The result is not only further enhancement of the rate of osseointegration, but also up to 30% higher implant stability due to increased mechanical bioanchorage of the implant in the surrounding bone. The combined effect of TiUnite® and the groove takes the Nobel Biocare implants and Immediate Function™ to a new level of effectiveness, and increases safety of implant treatment, especially in non-optimal bone situations.
Extending your range with NobelSpeedy™
Immediate Function™ protocols can be used together with all our implants, provided that primary stability is achieved at the time of implant placement. However, in compromised bone conditions it's sometimes difficult to achieve sufficient implant stability. That's why NobelSpeedy™ is specially designed to circumvent this problem.
The NobelSpeedy™ implant features a narrow implant tip with engaging threads. This enables you to place the implant in under-prepared sites and let it work as an osteotome. In this way, good mechanical stability can also be achieved in soft bone, making it possible to load the implant without waiting for the healing process to be completed. Although particularly effective in soft bone conditions, the NobelSpeedy™ design results in good insertion characteristics in all types of bone. This makes it an easy-to-use implant for various types of indications.
Bone grafting yes or no
A dental implant is a screw with a diameter and a length. Do not forget that the purpose of an implant is to support a dental prosthesis and if it is too small or too thin, its resistance to masticatory forces will be less. It is therefore common to use implants having at least 8 mm in length and 3.5 mm in diameter. This requires that the bone in which we will ask our implant has at least the length of the implant chosen and a width greater so that it is completely surrounded by bone.This is why we define the lack of bone in both width and height.
Lack of bone height
Le problème du manque d'os en hauteur se pose différemment à la mandibule (machoire inférieure) et au maxillaire (machoire supérieure).The problem of insufficient bone height arises differently in the mandible (lower jaw) and maxilla (upper jaw).
1-In the mandible
Sur la partie antérieure de la mandibule, qui est la zone du menton, l'os se trouve toujours en quantité suffisante pour permettre la pose d'un implant dentaire.On the anterior part of the mandible, which is the area of the chin, the bone is always sufficient to allow the placement of a dental implant. At the rear, the lack of bone height is a more difficult problem, its resolution will involve more skill and experience of the practitioner who will speak, and claim the use of bone from the patient itself. Bone graft will only be achieved if the smaller implants may be used or the chin area does not allow itself to find a solution to the problem of the implant patient.2-In the maxilla.
Bone grafts in height are easier to perform by virtue of the quality of the bone at this level (more spongy bone of the mandible). On the front, if there is lack of bone height, it can provide. against by the posterior, we can solve the problem by grafting the sinus. This bone graft a portion of the sine called " sinus lift "is to fill the lower part of the sine to increase bone height.
It is useful when we have only a few millimeters of bone under the sinus and is the implant while simultaneously lifting the sinus. It entwines less postoperative but is limited in its indications.
Lack of bone width
Cette situation est plus facile à résoudre. This is easier to solve. Si il ne manque que très peu de largeur, il est possible d'élargir légèrement la crête osseuse en posant l'implant. If it lacks very little in width, it is possible to slightly widen the bone crest by placing the implant. Si le manque est un peu plus important, on utilse des biomatériaux (voir chapitre suivant) pour apporter de l'os et réaliser ainsi la greffe osseuse sans avoir besoin d'utiliser l'os du patient. If lack is a little more important, we used some biomaterialsto bring the bone and make bone graft and without the need to use the patient's bone. Pour un manque plus important et plus étendu, la résolution du problème passera par une "autogreffe", c'est-à-dire que l'on va prélever de l'os sur un " site donneur " du patient lui-même afin de le greffer sur la zone à implanter. For a lack larger and more extensive, solving the problem will require an"autograft", that is to say that we will take the bones to a "donor site" the patient himself to graft it onto the area to be implanted. Schéma d'une greffe en largeur
The axis of the dental implant
The problem of the axis of the implant is extremely important. It can sometimes be enough bone to implement, but following the crestal bone, the dental implant can emerge in a place that makes it difficult to use or for which the esthetic is not satisfactory.To solve this problem, we realized a small bone graft that allows the implant axis in a more usable at all levels.
