Summary

Modified socket shield therapy (SST) has been proposed to preserve the facial plate and peri implant tissues. Whether spontaneous healing after two stage modified SST provides outcomes comparable to grafted SST before delayed implant placement remains unclear.

Detailed description

There remains no consensus regarding management of the space adjacent to the retained shield-whether it should be filled with a biomaterial or left for spontaneous healing. Clinical observations suggest that healing may not always yield complete mineralized fill; instead, a soft tissue interface can develop along the internal aspect of the root fragment, potentially limiting bone formation within the defect. At present, it remains unclear whether placement of a bone substitute can reliably reduce or prevent this soft tissue ingrowth along the inner surface of the retained fragment, providing a rationale for controlled comparisons of grafted and nongrafted two stage SST protocols. Therefore, the present controlled clinical study was designed to compare SST with xenograft combined with MPM augmentation versus SST alone, followed by delayed implant placement after a 6 month healing period. The study evaluated soft tissue ingrowth as key healing outcomes, alongside histologic findings and implant related parameters, including implant stability, as well as the incidence and management of procedure related complications.

Conditions

• Socket Shield Technique Implant Placement
• Socket Shield Technique
• Dental Implant
• Bone Grafting
• Delayed Implant

Interventions

Type	Name	Description
PROCEDURE	Socket Shield Technique	No grafting material was placed, and the socket was closed with a figure-of-eight suture to stabilize the clot
PROCEDURE	Socket Shield Technique	The xenograft/MPM mixture was gently packed into the shield-associated space/socket without excessive compression, and the socket was sealed and stabilized using a figure-of-eight suture technique
