Complications in sinus lift

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Bone Grafting Techniques

Background:

• Atrophic maxilla often requires bone grafting for dental implant placement.
• Maxillary sinus augmentation, introduced by Tatum and published by Boyne and James, addresses vertical and transversal bone deficiency.
• This procedure can be performed using lateral or crestal approaches.

Purpose of the Study:

• To evaluate the efficacy of maxillary sinus augmentation as a preprosthetic technique.
• To highlight the importance of preoperative anatomical assessment in reducing complications.
• To review the success rates and potential complications of the procedure.

Main Methods:

• Review of existing literature on maxillary sinus augmentation procedures.
• Analysis of surgical approaches (lateral vs. crestal).
• Examination of reported outcomes, including bone augmentation and implant osseointegration.

Main Results:

• Maxillary sinus augmentation demonstrates good results for bone augmentation and implant osseointegration.
• Infectious complications occur in a small percentage of patients (3.5%–10.5%).
• Preoperative assessment of sinus anatomy significantly reduces complication rates.

Conclusions:

• Maxillary sinus augmentation is a successful preprosthetic technique for the edentulous posterior maxilla.
• Careful preoperative evaluation of sinus anatomy is essential for minimizing risks.
• The procedure offers a reliable solution for implant rehabilitation in atrophic maxillae.
