Critical design errors in maxillary subperiosteal implants

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Biomaterials Engineering

Background:

• Maxillary full arch subperiosteal implants provide support for dental prostheses.
• Indications include advanced maxillary atrophy with specific stable bony support areas.
• Historical data indicates lower success rates for implants placed before 1985.

Purpose of the Study:

• To present outcomes of over 300 maxillary full arch subperiosteal implant cases.
• To emphasize the importance of anatomical and physiological understanding for optimizing results.
• To compare historical success rates with contemporary outcomes.

Main Methods:

• Review of over 300 maxillary full arch subperiosteal implant cases with up to 12 years in function.
• Analysis of patient selection criteria based on anatomical landmarks.
• Emphasis on the underlying anatomical and physiological principles.

Main Results:

• Over 300 cases with up to 12 years in function are presented.
• Success rates are improved compared to earlier cases placed before 1985.
• Proper patient selection and understanding of anatomy are crucial for success.

Conclusions:

• Maxillary full arch subperiosteal implants are a viable option for severe maxillary atrophy.
• Optimized results depend on a thorough understanding of anatomical and physiological factors.
• Modern techniques and patient selection have led to improved success rates.
