The fear of postoperative pain is often mentioned by patients as one of the factors that is most frequently associated with dental implants. To reduce this factor, a single oral dose of 25 mg dexketoprofen trometamol (DKT) or placebo was administered 15 minutes before implant surgery. One hundred patients who required single-implant treatments were randomly assigned to 1 of 2 blinded groups. The patients in the test group were given 25 mg DKT (DKT group), and those in the control group were given 500 mg vitamin C as a placebo (PLACEBO group). A subjective visual analogue scale of 100 mm in length was used to evaluate pain. Inflammation and complications were assessed using a 5-point Likert scale. An analysis of variance, t-tests, and a Mann-Whitney U test were performed. Among the 100 patients, 83 completed the study (there were 8 dropouts in the PLACEBO group and 9 in the DKT group). The patients who received DKT reported a lower pain intensity during the immediate postoperative period. The inflammatory response was weaker in the DKT group than the control group at 48 hours, but bleeding was greater. There were no other complications in either of the groups. In conclusion, the preemptive use of 25 mg soluble DKT administered orally 15 minutes before implant surgery can reduce the severity of immediate postoperative pain.

Background: Tooth autotransplantation is a valid method for replacing nonrestorable teeth. This study aimed to assess mid-term survival and success of autotransplanted third molars and the clinical periodontal parameters and factors predicting successful periodontal attachment apparatus regeneration. Methods: In total, 36 patients who had undergone extraction and subsequent autotransplantation of 36 third molars using virtual planning and computeraided rapid prototyping models by an oral surgeon and endodontist were eligible. Probing pocket depth (PPD), gingival recession (REC), clinical attachment level (CAL), pulpal and periapical healing, root resorption, and radiographic bone loss (RBL) were evaluated. Additionally, a questionnaire evaluated patient-reported outcomes. Results:The mean age of the participants was 30.2 years with a mean followup duration of 29.42 ± 14.56 months. The overall survival and success rates were 97.2% and 91.7%, respectively. No statistically significant differences were found in success and survival rates between open and closed apex groups or between compromised and intact buccal bone groups. No signs of pulp necrosis were found in the open apex group. Progressive replacement resorption was detected in one closed apex case. The mean PPD was 2.7 ± 0.45 mm for all transplanted teeth. REC was 0.13 mm higher in transplanted teeth than in previous hopeless teeth. CAL changes were neither clinically relevant (−0.17 ± 0.66 mm) nor statistically significant. The reported patient satisfaction was high.Conclusions: Autotransplantation of third molars is a predictable treatment method, with a 2.5-year cumulative tooth survival and success of 97.2% and 91.7%, respectively, which were not influenced by recipient site integrity or root development.

Introduction: Digital technology has been progressively introduced into tooth autotransplantation to enhance both treatment planning and surgery. The aim of this report was to describe a novel protocol for fully guided tooth autotransplantation. Methods: This report includes 10 consecutive patients treated with a complete virtual planning and a multidrilling axis surgical guide in combination with the computer-aided rapid prototyping model. Results: All transplanted teeth fulfilled the criteria for success over a mean follow-up duration of 13.1 months. No signs of progressive root resorption or pain were found during follow-up. One case required minimal adjustment of the surgical stent to allow correct seating, whereas a second case could not be performed fully guided because of limited mouth opening. Conclusions: Our protocol for fully guided tooth autotransplantation is a viable option that involves minimal bone preparation in a short surgical time. Future research should focus on further investigation of the benefits of this novel protocol in a larger sample.

Background The purpose of this study was to investigate the influence of vestibular depth (VD) on the outcomes of root coverage therapy. Methods Patients presenting gingival recession defects (GRD) with a minimum depth of 2 mm underwent root coverage therapy consisting of a coronally advanced flap plus a connective tissue graft (CAF + CTG). Clinical examinations were performed, and intraoral scans were obtained at baseline, 3 and 6 months after surgery to assess changes in probing depth (PD), keratinized tissue width (KTW), recession depth (RD), GRD area, marginal gingival thickness (MGT), and VD. The influence of VD on percentage of root coverage (%RC) and the likelihood of achieving complete root coverage (CRC) were explored. Results A total of 20 patients were enrolled, and 44 teeth were treated. RD decreased and MGT increased in all treated sites. At 6 months, mean %RC was 87.47 ± 18.37 and CRC was observed in 61.4% of sites. Mean baseline VD was 7.33 ± 2.67 mm. Mean VD reduction from baseline to 6 months was 1.98 ± 1.27 mm. %RC and CRC were significantly correlated with baseline VD. Each additional 1 mm of baseline VD implied a gain of 6.58% for %RC and increased 2.75 times the probability of achieving CRC. Narrow baseline KTW and mandibular arch location were associated with inferior treatment outcomes. Conclusion Lower %RC and likelihood of achieving CRC can be expected after root coverage therapy via CAF + CTG in sites presenting a shallow vestibulum.
