Polylactic/Polyglycol Copolymer Versus Calcium Sulfate as Grafting Materials Around Immediate Implants

Abstract

Immediate implant placement in molar sites was always accompanied by self­ contained marginal defects at all aspects due to discrepancy between the implant and socket size. The main objective of the current study was to evaluate two alloplastic materials for grafting of peri-implant defects around dental implants inserted in fresh extracted socket of lower molar teeth.

This study comprised 12 implants installed in II patients They were assigned in one of two groups:

Group A:

This group included 6 patients receiVIng 6 immediately placed implants augmented with calcium sulfate grafting material to fill the peri-implant gaps.

GroupB:

This group included 5 patients recetvmg 6 immediately placed implants augmented with Polylactic-polyglycolic copolymer to fill the peri-implant gaps.

All the implants were evaluated clinically and radiographically. Radiographic evaluation of the peri-implant bone height and density was performed using digital panoramic radiographs 48 hrs as well as at I ,2 and 3 months after implant placement.
