Department of Clinical and Experimental Medicine, University of Foggia, 71122 Foggia, Italy.

Purpose: To evaluate the accuracy of computer-aided dental implant positions obtained with mucosal-supported templates as compared to Three-Dimensional (3D) planning.

Materials And Methods: One-hundred implants were inserted into 14 edentulous patients using the All-on-4/6 protocol after surgical virtual planning with RealGUIDE, 3DIEMME, and Geomagic software. After 6 months, three-dimensional neck (V) and apex (S) spatial coordinates of implants and angle inclination displacements as compared to virtual plans were evaluated.

Results: The S maxilla coordinates revealed a significant discrepancy between clinical and virtual implant positions (-value = 0.091). The V coordinates showed no significant differences (-value = 0.71). The S (-value = 0.017) and V (-value = 0.038) mandible coordinates showed significant discrepancies between the clinical and virtual positions of the screws. Implant evaluation showed a 1-mm of the horizontal deviation in the V point and a 1.6-mm deviation in the S point. A mean 5° angular global deviation was detected. The multivariate permutation test of the S (-value = 0.02) confirmed the difference. Greater errors in the mandible were detected as compared to the maxilla, and a higher S discrepancy was found in the posterior jaw compared to the anterior section of both the mandible and maxilla.

Conclusions: Computer-aided surgery with mucosal-supported templates is a predictable procedure for implant placement. Data showed a discrepancy between the actual dental implant position as compared to the virtual plan, but this was not statistically significant. However, the horizontal and angle deviations detected indicated that flap surgery should be used to prevent implant positioning errors due to poor sensitivity and accuracy in cases of severe jaw atrophy.

Correlation Between Maxillary Canine Impaction and Facial Biotype.

J Craniofac Surg 2019 Jun;30(4):1044-1048

Department of Clinical and Experimental Medicine, University of Foggia, Foggia.

Aim: The etiology of teeth impaction is still not fully understood, despite that cofactors have been considered important to develop such a clinical picture. The aim of the authors' paper was to investigate about facial biotype, about the values of inclination of the upper cuspid axis to the perpendicular to Frankfort-horizontal plane and about the distance "d" of the canine cuspid to occlusal plane: each factor was statistically compared. The authors also performed a comparative analysis on the radicular length of the left and right lateral incisors of subjects with impacted maxillary canine.

Methods: The authors recruited with "cluster sampling" randomization more than 30 patients, then refined to 25 after the application of exclusion criteria. Specific values were carried out by x-rays: the authors calculated both the α and β angles, the intermaxillary angle, the distance "d" and the inclination of upper cuspid axis to the perpendicular-to-Frankfort-horizontal plane. Spearman rank correlation coefficient or Spearman rho (ρ) was used as statistical methods.

Results: The authors' results assessed that the inclination of the upper cuspid axis to the perpendicular-to-Frankfort-horizontal plane showed a statistically significant inverse correlation with the intermaxillary angle.

Conclusion: The authors' data clearly indicate that hyperdivergence is a key-factor that will certainly support the eruption path of canine cuspid: in this light, the treatment of tooth impaction in hyperdivergent subjects can be considered as predictive for a good prognosis.

Eradication of hairy mouth after oncological resection of the tongue and floor mouth using a diode laser 808 nm. Postoperative pain assessment using thermal infrared imaging.

Lasers Surg Med 2019 08 6;51(6):516-521. Epub 2019 Jan 6.

Department of Morphology, Experimental Medicine and Surgery, University of Ferrara, Ferrara, Italy.

Objectives: Vascularized soft tissue flaps are often harvested from hair-bearing areas, such as the radial forearm or anterolateral thigh, making their use in oral reconstruction problematic due to postoperative hair growth. The presence of intact hair follicles in free tissue transfer and continued hair growth at the recipient site can result in difficulties with oral hygiene, intraoral irritation, food trapping, and patient distress. This study was to evaluate the intraoral efficacy and safety of a diode laser 808 nm when used for hair removal.

Materials And Methods: Sixteen male patients, between 2010 and 2017, were referred for intraoral hair eradication with a history of squamous cell carcinoma of the tongue or floor mouth resection. An 808 nm diode laser (Stark 808, Plume s.r.l., Rome, Italy) was used to remove the intraoral hair. Each patient received a total of six treatments at 4-week intervals. Perifollicular pain was quantified by the physician using visual analog scales. Follow-up visits were scheduled at 1, 4, and 6 days to check the state of the tissues. The recall program included assessments of VAS, erythema, and perifollicular temperature. Patients were followed up for long-term assessments at 6 and 12 months after the final treatment session.

Results: All patients presented well with no occurrence of symptoms, indicating possible perifollicular inflammation. Based on the VAS scores, very mild discomfort during laser irradiation was recorded in all patients, with average pain score of 10.98 ± 1.42. No pain or discomfort was recorded 1, 4, and 6 days after the procedure. After the third pulse of light was applied, the average temperature with standard deviation of the hair tip with both the dark and light skin was 74.4 ± 11.7°C. The difference in temperature before the procedure (basal measurement 37.5 ± 2.8°C) and immediately after laser irradiation was 36.9 ± 3.7°C. The difference in temperature disappeared after 0.29 seconds, and no temperature increase was recorded on days 1, 4, or 6. In all the patients, the hair clearance between baseline and the 6th treatment, the 6-month follow-up, and the 12-month follow-up rated as significant P < 0.05. The mean percentage of hair reduction was 97.3% at 12 months.

Conclusion: In conclusion, the clinical findings demonstrate the safety and efficacy of the 808 nm diode laser system for intraoral hair removal Lasers Surg. Med. 51:516-521, 2019. © 2019 Wiley Periodicals, Inc.

Preliminary Study to Evaluate Marginal Bone Loss in Cases of 2- and 3-Implant-Supported Fixed Partial Prostheses of the Posterior Mandible.

J Craniofac Surg 2019 Jun;30(4):1068-1072

Department of Otolaryngology, Tel-Aviv Sourasky Medical Center, Sackler Faculty of Medicine, Tel-Aviv University, Tel-Aviv, Israel.

Purpose: The purpose of this study was to evaluate, by radiographic examinations, the marginal bone resorption around implants in cases of 2 and 3 implant-supported fixed partial prostheses (FPPs) at the posterior mandible.

Methods: A retrospective study of 41 patients (23 males, 18 females) of an average age of 67 years (range, 53-85), with 2 and 3 implants-supported FPPs in the posterior mandible that were treated during 2006 to 2015. The mean follow-up time was 6.32 years (range, 2-10). Twenty-four patients had FPPs on 2 implants (a total of 48 implants). Seventeen patients had FPPs on 3 implants (a total of 51 implants). Clinical and radiographic follow-up examinations were performed. All radiographs were analyzed for changes in marginal bone height surrounding the implants.

Results: The mean marginal bone loss around the most mesial implant was slightly higher in the 2-implant group (0.833 mm) compared with the 3-implant group (0.431 mm). The correlation between the mean marginal bone loss around the most mesial implant and the number of implants was of borderline value (P = 0.055).

Conclusions: Considering the limitations of this preliminary study, the authors found that the mesial implant in the 2-implant group is more susceptible to marginal bone loss.

Bilateral Hyperplasia of the Coronoid Process in Pediatric Patients: What is the Gold Standard for Treatment?

J Craniofac Surg 2019 Jun;30(4):1058-1063

Università Degli Studi di Milano.

Objectives: The aim of this systematic review of the literature is to describe treatment options for bilateral coronoid process hyperplasia in pediatric patients, to describe etiologic and diagnostic correlations with the treatment, and to evaluate long-term follow-up treatment outcomes.

Methods: A systematic revision of the literature was performed in the Medline, PubMed, Cochrane library, and Embase database up to December 5, 2017. Predetermined Medical Subject Heading keywords were used: "bilateral" or "monolateral" and "coronoid" or "coronoid process" and "hyperplasia" and "temporomandibular joint" or "tmj" and "ankylosis" or "trismus" and "treatment." Results were recorded following PRISMA guidelines.

Results: The systematic research produced 1459 results excluding duplicates. Two additional studies from "Grey literature" were also considered. After application of inclusion and exclusion criteria, 38 articles were selected for a qualitative synthesis. Data regarding sex and age of presentation were collected and summarized in a study flow diagram.

Conclusion: It is possible to conclude that early diagnosis is fundamental to restore stomatognathic multifunction. There is lack of longitudinal studies presenting long-term follow-up to determine treatment stability. Coronoidectomy might be considered gold standard treatment for this pathologic condition.
