Influence of the loading protocol and platform switching in two-implant bar-retained overdentures: 3-year results from a randomized controlled equivalence clinical trial.

OBJECTIVES: To test the null hypothesis that vertical peri-implant bone level alterations (ΔIBL) are equivalent in immediately (IL) and 3-month post-placement (DL) loaded implants in mandibular implant overdentures (IODs) on two implants. MATERIALS AND METHODS: Thirty-two patients receiving two interforaminal implants, one with a platform-switched and one with a platform-matching abutment were randomly assigned to the IL or DL group (allocation ratio 1:1). All implants were primarily splinted with chairside-customized bars, converting the existing removable complete dentures to IODs. Standardized radiographs were recorded. The influence of the loading protocol (IL vs. DL), implant platform (platform switched vs. platform matching), implant site (43 vs. 33), participant age (≤65 vs. >65 years), and definition of baseline (implant placement vs. implant loading) were analyzed, applying linear regression analyses (α = 0.05). The equivalence range was [-0.4; 0.4]. RESULTS: Three participants of the IL group were lost during follow-up. The overall mean ΔIBL was -0.96 ± 0.89 mm. The ΔIBL was equivalent in terms of the implant platform and implant site but not in terms of participant age (in favor of more elderly participants) and the loading protocol. A significantly smaller ΔIBL was observed in the IL when the baseline was considered to be implant placement (p = .017), but not when it was considered to be implant loading (p = .084). CONCLUSION: Immediate loading of primary-splinted implants in two-implant bar-retained overdentures, seems beneficial relative to loading 3 months post-placement, with respect to ΔIBL. The ΔIBL were equivalent in terms of platform switching.

Program Director Attitudes Toward Acceptance of Pediatric Dentistry Entrustable Professional Activities (EPAs).

Purpose: To acquire comments on pediatric dentistry entrustable professional activities (EPAs) from pediatric dentistry residency program directors (PDs). Methods: An electronic survey invited PDs to evaluate 16 previously developed EPAs on whether they were critical to patient safety, resident education, or both. PDs were asked to evaluate a fully developed EPA to assess structure and clarity and describe barriers to EPA. Descriptive statistics were completed. Results: Forty-one of 103 PDs completed the entire survey. Eighty-five percent (36 of 42) of PDs believed EPAs are critical to pediatric dentistry education, and 81 percent (34 of 42) believed EPAs are critical to patient safety. Eighty-one percent of PDs would likely use EPAs when available. Seventy-five percent (31 of 41) of PDs reported that they have had a resident who would have benefited from a longer duration of training. Conclusions: The majority of pediatric dentistry residency program director participants surveyed reported that entrustable professional activities are critical to patient safety and resident education. EPAs may be a valuable option for assessing residents' readiness for graduation.

Development of entrustable professional activities for post-doctorate pediatric dentistry education.

PURPOSE: To identify the core components of pediatric dentistry defining entrustable professional activities (EPAs) representing the profession. METHODS: Potential core components of pediatric dentistry and corresponding domains were identified through review of literature and existing pediatric dentistry standards. A modified Delphi technique was utilized to rate these candidate EPAs to achieve consensus around prioritized EPAs. RESULTS: Eleven participants participated in all three rounds of the Delphi. After three rounds, 16 candidate EPAs reached consensus for pediatric dentistry. Each EPA fell into one of four domains: "assessment and planning," "provision of care," "behavior guidance," and "professional development." An original candidate EPA focused on non-pharmacological behavior guidance was deemed too broad by the Delphi. This EPA was subsequently developed into three separate components on nitrous oxide analgesia, moderate sedation, and general anesthesia. CONCLUSIONS: Prioritized EPAs will help define the essential activities of the profession and provide a framework for creating assessments to ensure that graduating pediatric residents are ready for unsupervised practice.
