In the past, implant treatment was merely surgically driven, with osseointegration constituting success. Nowadays we have greater expectations. We need to provide restoratively driven implant treatment now. This further considers the implant’s and prosthetic crown’s aesthetics and long-term stability. Below we will cover some points covered at our Master Implant Program in Melbourne and Adelaide.
Restoratively Driven Factors
The implant’s location within the jaw should help accommodate the prosthetic crown’s position. The crown should sit within the arch while enhancing oral function and aesthetics. Our specialist prosthodontist and periodontist lecturers discuss three main restoratively driven factors:
- Bone volume
- Soft tissue
- Restoratively driven site development
We know that soft tissue is largely dependent on the underlying hard tissue morphology. Therefore, it is important to have enough soft tissue volume and sound bone to sculpt the site, and allow successful osseointegration.
For the implant to sufficiently support the prosthetic crown, its location must be considered in all dimensions. Our hands-on implant courses provide you with guidance from dental specialists so that you can achieve the right angulation.
Apico-Coronal
As a rule of thumb, the implant should lie 2-3mm from the gingival margin (Cooper & Pin-Harry, 2013) (Cooper, De Kok, Reside, Pungpapong, & Rojas-Vizcaya, 2005). This is not a set rule, however, as different implant systems vary on their recommended crestal position. There must also be enough inter-arch space to prevent the crown’s occlusal height interfering with occlusion (Cooper & Pin-Harry, 2013).
Bucco-Lingual
Position the implant 1mm behind the imaginary line of emergence profile of the adjacent teeth (Evans & Chen, 2007).
Mesio-Distal
Avoid placing the implant too close to adjacent teeth or other implants. This would increase the risk of bone resorption, poor osseointegration, and interdental bone and papillae loss. This could impact the restorative results, and even cause loss of the implant or tooth. Therefore, the distance from such structures should be at least 1.5 mm from a tooth or 3 mm from an adjacent implant (Cooper & Pin-Harry, 2013).
Angulation
Angle the implant so that it is fully seated in bone, reduces stress at the site, and helps create the prosthetic crown’s emergence profile.
Our Master Implant Program trains and guides you to achieve the ideal angulation for your dental implants.
