Longitudinal report on hydroxyapatite-coated implants and advanced surgical techniques in a private practice

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Science
• Dental Implantology

Background:

• Hydroxyapatite-coated dental implants offer enhanced osseointegration.
• Oral surgery practices frequently encounter patients with bone deficiencies requiring advanced implant solutions.
• Long-term clinical data on implant survival rates in compromised patients are crucial for evidence-based practice.

Purpose of the Study:

• To evaluate the clinical success and survival rates of 690 hydroxyapatite-coated dental implants.
• To identify factors influencing implant success, including patient conditions and implant characteristics.
• To assess implant performance in a cohort with significant bone height or width limitations.

Main Methods:

• Retrospective analysis of 690 hydroxyapatite-coated dental implants placed from 1985 to 1993.
• Inclusion of patients with compromised bone conditions, necessitating advanced surgical techniques.
• Evaluation of success based on factors such as implant position, patient sex, and implant length.

Main Results:

• A cumulative survival rate of 96.5% was achieved up to 88 months post-placement.
• Shorter implants demonstrated a higher likelihood of failure compared to longer implants.
• Implant success was influenced by factors including anatomic position and implant length.

Conclusions:

• Hydroxyapatite-coated dental implants demonstrate high survival rates even in patients with compromised bone conditions.
• Implant length is a critical factor, with shorter implants associated with increased failure risk.
• Advanced surgical procedures can facilitate successful dental implant placement in challenging oral and maxillofacial cases.
