Patient-reported Outcome Measures Comparing Static Computer-aided Implant Surgery and Conventional Implant Surgery

Patient-reported Outcome Measures (PROMs) Comparing Static Computer-aided Implant Surgery (s-CAIS) and Conventional Implant Surgery (CIS) for Single-tooth Replacement: A Randomized Controlled Trial

The aim of this randomized controlled trial was to compare PROMs in patients receiving single tooth replacement in posterior sites by s-CAIS and CIS.

Since current patient-reported outcome measures (PROMs) evidence related to static computer-aided implant surgery (s-CAIS) compared with conventional implant surgery (CIS), particularly in partial edentulous patients, were still limited. The aim of this randomized controlled trial was to compare PROMs in patients receiving single tooth replacement in posterior sites by s-CAIS and CIS.

Inclusion Criteria:

• Healthy or well-controlled systemic disease (ASA classification I,II)
• A partially edentulous ridge in the premolar-molar region with existing two-sided interproximal as well as antagonist contacts
• No sign of acute oral infection
• Periodontally healthy (or successfully treated)
• More than 2 mm of keratinized gingiva at the site of surgery
• Sufficient bony ridge for implant placement with or without simultaneous bone grafting

Exclusion Criteria:

• Diabetes mellitus
• Smoking more than ten cigarettes per day
• Pregnancy
• Psychiatric disorder
• History of radiation therapy at head and neck area and chemotherapy
• Bony pathologies, namely osseous dysplasia, odontogenic cyst, tumor
• History of soft tissue grafting at the prospective implant site
• Inadequate bony ridge with the need of bone augmentation prior to implant placement
