Inter-implant Papilla Changes Following Anterior Immediate Tooth Replacement with Socket Shields: A 1- to 10-Year...

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Preserving inter-implant papilla and bone height is crucial for aesthetic outcomes in anterior dental implantology.
• The socket shield (SS) technique is a proposed method to maintain these tissues during immediate implant placement into extraction sockets.

Purpose of the Study:

• To evaluate the efficacy of the socket shield (SS) technique in preserving inter-implant papilla and bone height.
• To assess the clinical success of implants placed using the SS technique in anterior adjacent sites.

Main Methods:

• Retrospective study analyzing clinical and radiographic records of 23 patients.
• Evaluation of 31 implants placed with SS and 7 implants placed without SS in immediate extraction sockets.
• Mean follow-up period of 41.5 months.

Main Results:

• High clinical success rates observed: 96.8% for implants with SS and 100% for implants without SS.
• Mean reduction in inter-implant papilla height was -0.40 mm and bone height was -0.46 mm.
• Factors like placement timing, shield number, shape, and crestal level did not significantly affect tissue height changes (P > .05).
• Supracrestal shield placement, U-shape, and shield-to-implant contact were associated with increased exposure risk.

Conclusions:

• The socket shield (SS) technique is a viable treatment option for maintaining inter-implant papilla in adjacent anterior implant situations.
• While effective for tissue preservation, careful consideration of shield positioning and shape is needed to minimize exposure.
• The SS technique demonstrates promising results for achieving successful aesthetic and functional outcomes in complex implant scenarios.
