Study Details

Study Description

Brief Summary

There is an angle between the intersection of the incisal long axis perpendicular to the palate or the occlusal plane, and the long axis of the root. When this relation is shifted more palatal, where the incisal plane line will be at the cingulum position or slightly palatal to it, it is named the safe angle position. The more palatal relocation to the cingulum is performed according to the availability of palatal bone, the occlusion with the opposing dentition, the type of the restoration (screw vs cemented).

The possibility of having a specific safe angle to place implants opens new interesting perspectives for immediate placement of dental implants.

The aim of the present study was to demonstrate how immediate implants in the safe angle position can be predictably achieve proper implant positioning, better esthetics and emergence profile as well as less stresses on the implant.

Condition or Disease Intervention/Treatment Phase
  • Other: Implant placement in the safe angle position in the anterior maxilla

Detailed Description

Immediate implants are implants inserted immediately after surgical extraction of the teeth to be replaced. Creation of an anatomically correct emergence profile is one of the most important aspects in providing an esthetically pleasing implant-supported restoration. Dentists understand the risks involved when restored prostheses are subjected to non-axial loading. It has always been recommended to direct occlusal loads as close to the long axis of the fixture as possible. However, it is known that the loading on angled abutments is mostly off-axis, which raises the concern of how angled abutments generally perform with such an unfavourable loading regimen.

There is an angle between the intersection of the incisal long axis perpendicular to the palate or the occlusal plane, and the long axis of the root. When this relation is shifted more palatal, where the incisal plane line will be at the cingulum position or slightly palatal to it, it is named the safe angle position. The more palatal relocation to the cingulum is performed according to the availability of palatal bone, the occlusion with the opposing dentition, the type of the restoration (screw vs cemented).
