Study Notes

Occlusal Plane and Implant Restoration

The orientation of the occlusal plane is crucial when restoring an implant, especially with a steep curve of Spee
A steep curve can cause interferences during lateral expressive movements
The orientation of adjacent teeth to the space is also important, considering esthetic and functional issues

Implant Space and Restoration

The space for the implant is from the soft tissue on top of the implant to the occlusal of the opposing tooth
There are two types of crowns: screw-retained and cement-retained
The type of restoration is determined by the space available, not by the bone position

Forces on Implant

Forces on the implant should be planned to be down the long axis of the implant to avoid shear and tensile forces
Software is used to plan the implant and determine the forces on the restoration

Clinical Exam Considerations

Pre-implant considerations include the patient's existing occlusion, occlusal plane, and tooth orientation
The proximity of adjacent teeth and their orientation are also important factors
A clinical exam should include evaluating the patient's existing vertical dimension of occlusion

Additional Factors to Consider

The arch relationship (Class I, II, or III) and the patient's range of motion and occlusal scheme
The TMJ status and arch form (e.g., ovoid, squarish, triangular)
The location of missing teeth and their impact on the restoration plan
Lip line and smile line considerations, which vary by age and sex

Team Approach and Patient Education

A team approach is essential in implant restoration to avoid unwanted forces and ensure a good prognosis
Patients should be educated about the importance of occlusal principles and the need to address underlying issues before restoring an implant
Dental students should learn to assess the entire oral situation and prioritize the patient's needs accordingly
