Consensus Statement
Surgical Planning and Procedures

The objective of this study was to systematically evaluate the scientific literature for patient-reported outcome measures (PROMs) in static computer-aided implant surgery (s-CAIS). A PICO strategy was executed using an electronic (MEDLINE, EMBASE, CENTRAL) plus manual search up to 06-15-2017 focusing on clinical studies investigating s-CAIS with regard to patients’ pain & discomfort, economics and/or intraoperative complications. Search strategy was assembled from multiple conjunctions of MeSH-Terms and unspecific free-text words. Assessment of risk of bias in selected studies was made at a trial level applying the Cochrane Collaboration Tool and the Newcastle-Ottawa Assessment Scale, respectively. The systematic search identified 112 titles. Seventy abstracts were screened, and 14 full texts were included for analysis. A total of 484 patients were treated with s-CAIS for placement of 2,510 implants. Due to the heterogeneity of the included studies, meta-analyses could not be performed.

Consensus Statements
  • It cannot be stated that s-CAIS, in terms of pain & discomfort, economics, and intraoperative complications, is beneficial compared with conventional implant surgery. 
    This Consensus Statement is based on four RCTs, four prospective Cohort Studies, five retrospective Cohort Studies, and one Case Series.
Clinical Recommendations
  • However
    1. Based on PROMs, economics, and complications, there is no contraindication to use s-CAIS instead of conventional implant surgery.
    2. Flapless s-CAIS may be beneficial in fully edentulous cases in relation to postoperative pain intensity compared with open-flap procedures.
    3. Flapless s-CAIS may lead to implant placement outside the zone of keratinized mucosa; therefore, the quality and quantity of the keratinized mucosa must be assessed before planning s-CAIS.
