Sinus floor elevation via the maxillary premolar extraction socket with immediate implant placement: a case series

Area of Science:

• Dental Implantology
• Oral Surgery
• Periodontology

Background:

• Immediate implant placement in maxillary premolars near the sinus floor presents challenges due to limited osteotomy depth.
• Traditional approaches often involve staged procedures or independent use of socket preservation and sinus elevation techniques.

Observation:

• A novel technique combining immediate implant placement in fresh extraction sockets with simultaneous bone-added osteotome sinus floor elevation was applied to five maxillary premolars.
• The procedure involved atraumatic extraction, socket debridement, osteotomy preparation, particulate bone grafting for sinus elevation with osteotomes, and subsequent implant placement.

Findings:

• All five implants were successfully placed and restored after a minimum 6-month healing period.
• Radiographic evaluation at restoration showed bone integration from the apical portion to the coronal threads.
• Implants demonstrated successful healing and function for 6 to 12 months without complications.

Implications:

• The combined technique of immediate implant placement and simultaneous osteotome sinus floor elevation is an effective approach for managing dental implants in close proximity to the maxillary sinus.
• This combined method can significantly shorten treatment duration for patients requiring implants in the posterior maxilla.
• It allows for the placement of implants with optimal length, enhancing stability and long-term prognosis.
