ABSTRACT: Background: Treatment planning for implants includes a through radiographic and clinical examination. This study compared ridge mapping, direct surgical exposure and CT scan for alveolar ridge assessment before dental implant insertion. Materials & Methods: The present study was conducted on 60 patients who were selected for dental implants placement of both genders. Patients were divided into 3 groups of 20 each. In group I, direct surgical exposure, in group II CT scan and in group III ridgemapping procedure was performed at 3 mm and 6 mm from alveolar crest. Results: The mean measurement of alveolar ridge at 3 mm in group I was 3.92 mm, in group II was 4.02 mm and in group III was 3.90 mm. The difference between groups was non- significant (P> 0.05). The mean measurement of alveolar ridge at 6 mm in group I was 6.46 mm, in group II was 6.54 mm and in group III was 6.44 mm. The difference between groups was non- significant (P> 0.05). Conclusion: Authors found that all the methods revealed similar results hence any of these methods may be used in alveolar ridge assessment before inserting dental implants.
