Immediate Implant Placement in the Esthetic Zone

Summary

This study aims to examine dimensional alveolar ridge alterations and prevent buccal plate resorption and soft tissue recession following immediate implant placement in extraction sockets in the maxillary esthetic zone using different socket morphology-guided treatment modalities.

Expected results of the study are:

* To have found the optimal materials and GBR procedures modalities for buccal plate resorption degree reduction;
* Soft tissue recession and best esthetic result achievement. There will be possibilities to study socket morphology influence on final esthetic result achievement.

Conditions

• Unspecified Atrophy of Edentulous Alveolar Ridge

Interventions

PROCEDURE

Immediate implant placement with simultaneous bone grafting

* Flapless surgery is used for surgical implant installation. * Implant is placed in the cingulum position of adjacent teeth incisal edge. * After placement of optimal implant the remaining gap between the implant and the surrounding bony walls should be at least 2 mm or should be need for GBR of buccal plate outside the socket. * Two types of bone graft materials will be applied for two groups of patients: Group I - natural bovine bone grafting material + resorbable natural soft tissue membrane; Group II - processed human allograft + resorbable natural soft tissue membrane . Crown can be fixed on abutment if there is initial stability under 35 Ncm insertion torque. If insertion torque will be less, crown should be bond to neighboring teeth using composite material.
