Horizontal Ridge Augmentation: A Comparison between Khoury and Urban Technique

Area of Science:

• Dental Implantology
• Periodontology
• Regenerative Medicine

Background:

• Alveolar ridge defects pose challenges for dental implant placement.
• Horizontal augmentation is crucial for achieving optimal implant stability and aesthetics.
• The Khoury and Urban techniques are established methods for horizontal bone augmentation.

Purpose of the Study:

• To systematically review and compare the clinical effectiveness of Khoury and Urban horizontal alveolar ridge augmentation techniques.
• To analyze bone gain and complication rates associated with each technique.

Main Methods:

• Systematic literature search of MEDLINE, SCOPUS, WOS, and CENTRAL databases up to July 2021.
• Independent review by two researchers.
• Descriptive analysis of six included studies due to heterogeneity precluding meta-analysis.

Main Results:

• Both Khoury and Urban techniques demonstrated effective horizontal bone gain.
• Khoury technique achieved 3.93–5.02 mm bone gain; Urban technique achieved 3.9–5.68 mm bone gain.
• Similar complication rates observed: infection (Khoury, 7%) and membrane exposure (Urban, 3.2–13.6%).

Conclusions:

• Both techniques are clinically effective for horizontal alveolar ridge augmentation.
• The current literature is limited, with a scarcity of direct comparative studies.
• Further research is needed to definitively compare the long-term outcomes and efficacy of these augmentation methods.
