The Root Membrane Technique: Human Histologic Evidence after Five Years of Function.

Area of Science:

• Dental Implantology
• Oral Surgery
• Periodontology

Background:

• The root membrane (RM) technique is increasingly utilized for immediate implant placement in the anterior maxilla.
• This study evaluates the long-term histologic outcomes of the RM technique.

Observation:

• A dental implant placed using the RM technique in the anterior maxilla was retrieved after five years.
• Histologic and histomorphometric analysis was performed on the retrieved specimen.

Findings:

• The buccal bone plate remained intact with no resorption, and a healthy periodontal ligament was observed.
• The implant achieved significant osseointegration (76.2% bone-to-implant contact).
• Bone regeneration was noted in the space between the root membrane and implant.

Implications:

• The RM technique demonstrates efficacy in preventing buccal bone resorption following immediate anterior maxilla implant placement.
• This technique supports long-term implant stability and osseointegration.
• Histologic evidence supports the clinical success of the RM technique in anterior maxilla reconstructions.
