Retrospective Study of Maxillary Sinus Augmentation Using Demineralized Tooth Block Bone for Dental Implant

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Regenerative Dentistry

Background:

• Maxillary sinus elevation is crucial for dental implants in posterior regions with inadequate alveolar bone.
• Autogenous bone grafts are biologically ideal but involve donor site morbidity.
• Block-type autogenous tooth bone graft material presents a viable alternative, minimizing patient discomfort.

Purpose of the Study:

• To evaluate the efficacy of block-type autogenous tooth bone graft material in maxillary sinus elevation procedures.
• To assess bone regeneration, implant stability, and patient outcomes.

Main Methods:

• A study involving 19 implant patients undergoing maxillary sinus elevation.
• Utilized demineralized tooth block bone graft material derived from extracted teeth.
• Evaluated sinus membrane elevation, alveolar bone height, and implant osseointegration via clinical and radiographic assessments.

Main Results:

• Demonstrated proportional increases in alveolar bone height correlating with graft material size.
• Observed long-term stability of the regenerated bone and implants.
• Reported no significant postoperative complications, including successful management of sinus membrane perforations.

Conclusions:

• Block-type autogenous tooth bone graft material exhibits excellent bone induction and biocompatibility for maxillary sinus lifts.
• This method provides a highly beneficial and predictable treatment option for enhancing alveolar bone height for dental implants.
• Offers a patient-friendly alternative to traditional autogenous bone grafting techniques.
