    Abstract Objectives: To assess the skeletal and dental maxillary transverse compensation (yaw) on the cone beam computed tomography (CBCT) three-dimensional reconstructed image of the skull in two groups of patients, both clinically affected by a class III malocclusion with deviation of the lower midline.
    Materials and methods: An observational retrospective study was designed to analyse differences in two groups of patients, the first one was composed by patients affected by horizontal condylar hyperplasia, the second one by patients affected by dento-skeletal asymmetric class III malocclusion. Each group was composed by 15 patients. Transverse analysis was performed by measuring five landmarks (three bilateral and two uneven) with respect to a mid-sagittal plane; sagittal analysis was performed by measuring the sagittal distance on the mid-sagittal plane between bilateral points. Means were compared through inferential analysis.
    Results: In the condylar hyperplasia group, all differences between the two sides were not statistically significant, nor for canines' difference (P = .0817), for molars (P = .1105) or for jugular points (.05871). In the class III group, the differences between the two sides were statistically significant for molars (P = .0019) and jugular points (P = .0031) but not for canines (P = .1158). Comparing the two groups, significant differences were found only for incisors' midline deviation (P = .0343) and canine (P = .0177).
    Conclusion: The study of the yaw on CBCT should be integrated into three-dimensional cephalometry and could help in differentiating the various malocclusion patterns.

    Abstract This study was performed to evaluate the reliability of peri-apical radiographs in determining peri-implant marginal bone level changes. The STROBE guidelines were followed. Marginal bone levels were measured at the time of implant insertion using a straight periodontal probe and using peri-apical radiographs. These intraoperative and radiographic measurements were repeated at the time of second surgery. All radiographs were analysed by two examiners blinded to the intraoperative measurements. To standardize the radiographic images, the long-cone parallel technique and a film-holding system were used. Intra-observer agreement and inter-observer variability were assessed using the intra-class correlation coefficient (ICC). Descriptive statistics, the t-test, and the Pearson correlation coefficient were also used. A total of 268 implants were inserted in 142 patients. Inter-observer agreement was 0.950; intra-observer variability was 0.980 and 0.973. The mean difference between the radiographic and intraoperative measurements was 0.50±1.55mm (range 0-8mm); the difference was statistically significant (P=0.000). A significant linear correlation was found between the marginal bone level changes evaluated intraoperatively and radiographically (P<0.005). Radiographic analysis significantly overestimated the level of peri-implant marginal bone compared to intraoperative measurements, but peri-apical radiographs are reliable in determining the bone level changes at different follow-ups.

    Abstract The aim of this report was to describe a new computer-guided technique for a controlled site preparation and palatal orthodontic miniscrew insertion using a dedicated software. A surgical guide was designed after planning the appropriate insertion sites on three-dimensional images created by the fusion of cone-beam computed tomography (CBCT) and digital dental model images. Pre- and postoperative CBCT images were compared and the angular, coronal, and apical deviations between the planned and the placed miniscrews were calculated. The mean coronal and apical deviations were 1.38mm (range: 3.48-0.15mm; standard deviation (SD): 0.65) and 1.73mm (range: 5.41-0.10mm; SD: 1.03), respectively, while the mean angular deviation was 4.60° (range: 15.23-0.54°; SD: 2.54). The present surgical guide allows a controlled and accurate palatal miniscrew placement in three dimensions.

    Abstract To date, no strong long-term data have been reported about new innovative clinical protocols to manage oral hygiene. An improper management of oral hygiene may lead to an increase in dental implant failure, and to an increase in infective complications in prosthetic rehabilitation. Personalized techniques are strongly required in dentistry and dental hygiene. A customized and personalized approach to oral hygiene is crucial in ensuring not only effective treatment, but also a careful analysis of the general health status of the patient involved in the therapeutic process. D-BioTECH is an acronym for Dental BIOfilm Detection Technique: it is based on a tailored approach to patients, ensuring that the operator actively interacts with the patient and their specific needs, especially during the domiciliary therapy. D-BioTECH is an approach to preventive care: in D-BioTECH, both dental hygienists and dentists play a central role. The use of a personalized approach to oral hygiene is the first step towards increasing implant and prosthesis survival rate; moreover, personalized medicine is strategic for managing and preventing the biological complications associated with several dental risk factors.

    Abstract Background: The aim of this study was to investigate the relationship between missing maxillary lateral incisors and the mesio-distal (MD) diameters of the teeth. Occlusal and skeletal characteristics of the patients have been analyzed.
    Methods: Seventy-nine patients were included in the study (permanent dentition, mean age: 13.7): 30 subjects with uni- or bilateral maxillary lateral incisors agenesis (study group, SG) and 49 patients with no maxillary lateral incisors agenesis (control group, CG). Orthopanoramics, plaster models and cephalometric analysis were used to perform the evaluations.
    Results: Compared to the CG, in the SG, most of the teeth had smaller MD diameter. In the bilateral agenesis subgroup, the average differences between teeth diameters were lower than those found by comparing them to the unilateral agenesis subgroup and to the SG. Overjet was reduced on average in the SG. In the SG were found less cases of cross-bite and scissor-bite, less frequency of impaction of at least one tooth and agenesis of other teeth, crowding only in the lower arch, square or ovoid arch shape in the upper arch and square in the lower arch, increased interincisal angle and decreased SN^GoMe.
    Conclusions: Upper lateral incisors agenesis, especially in cases of unilateral agenesis, is associated with MD teeth reduction. The agenesis of the upper lateral incisors is associated with a greater probability of agenesis affecting other teeth, molar and canine class II, reduced overjet and overbite, square or ovoid upper arch shapes, increased interincisal angle and reduced total divergence.

    Abstract Aim: To analyse the presence and prevalence of gnathologic problems in a sample of children, candidate for orthodontic treatment, and evaluate the relationship between psychological factors and gnathological problems. The purpose of this study was also to evaluate a simple protocol with specific psychological test and a questionnaire for the rapid diagnosis of gnathologic problems, useful for possible screening studies on a wider population.
    Materials and methods: Study Design: Observational, cross-sectional study. Among the patients coming for a first orthodontic evaluation 106 children, aged between 8 and 16 years, were examined. A complete orthodontic evaluation was performed in all patients; the RCMAS (Revised Children's Manifest Anxiety Scale) was used in the study to test the psychological condition, while the selected test for the diagnosis of gnathologic problems was the Fonseca Test. The prevalence of temporomandibular disorders (TMD) was evaluated with descriptive statistical analysis, and the eventually present correlation with a positive psycological test for anxiety has been evaluated with correlation parameters: c2 test of Pearson, and Cramer's V index.
    Results: The mean age of the children was 10.74 years. Females accounted for 55.66% of the total compared to 44.34% males. Signs and symptoms of TMD were present on average in 82% and 32% respectively. A remarkable amount of children also showed signs of psychological problems, mostly represented by anxiety. Positive correlation resulted between TMD (Fonseca scores) and increased overbite. Cross-correlations have been obtained, tested with Pearson c2 test and Cramer's V index, between level of anxiety, muscle pain on palpation, bad habits, and headache. The Class II subdivision molar class and altered canine relationship have been related to the presence of articular noise.
    Conclusion: The protocol largely respected the need for speed of administration, comprehensiveness and reliability that we set out to achieve. Limited correlations have been assessed between occlusal conditions and positivity to the administrated tests. Further studies are desirable to increase the sample population.

    Abstract Purpose: The primary objective of this study was to assess the accuracy of periapical radiographs in determining the peri-implant marginal bone level. The accuracy of the linear measurements on radiographs was considered as the absolute difference between the true, intraoperative or surgical marginal bone level measurements (direct bone measurements during surgical procedures) and the radiographic measured distances. The secondary aims were to identify the variables influencing the radiographic evaluation (arch: mandible/maxilla; implant location: anterior/posterior; timing of implant placement: "early delayed" and "prolonged delayed"). The influence of vestibular and palatal/lingual crestal bone levels was also investigated.
    Materials and methods: STROBE guidelines were followed. As soon as the implant was inserted, the marginal bone levels were recorded using a straight periodontal probe (intraoperative or surgical measurements). At the same time, periapical radiographs were taken. To standardize the radiographic images, periapical radiographs were acquired using the long-cone parallel technique and film holding system. All radiographs were analyzed by two examiners blinded to the surgical measurements. Intraclass correlation coefficient (ICC) was employed to assess the intraobserver and interobserver variability. The descriptive statistics, t test, and multivariate statistics were used; the threshold for statistical significance was P ≤ .05.
    Results: Two hundred sixty-eight implants were inserted in 142 patients. The interobserver agreement was 0.980; the intraobserver variability was 0.990 and 0.993. The mean difference between the radiographic and surgical measurements was 0.45 mm (range: 0 to 8 mm; SD: 1.76). Comparing the radiographic and surgical measurements, a statistically significant difference (P = .000) was detected. None of the variables considered (arch, implant location, and timing of implant placement) significantly influenced the accuracy. Neither the vestibular alveolar edge (P = .908) nor the lingual/palatal (P = .485) significantly influenced the accuracy.
    Conclusion: The periapical radiograph statistically significantly overestimates the level of peri-implant marginal bone compared with surgical measurements. The arch, implant location, timing of implant placement, and level of vestibular or lingual/palatal alveolar edge do not influence deviation between the intraoperative peri-implant marginal bone level measurements and the radiographically determined marginal bone levels.

    Abstract Aim of this study is the evaluation of the periodontal status of impacted canines treated by closed approach with ultrasonic surgery and orthodontic treatment compared with contralateral spontaneously erupted teeth. The periodontal conditions of the teeth adjacent to the canines (lateral incisors and first premolar) were also considered. 17 patients (9 females and 8 males; mean age: 15.2 years) with unilateral palatal impaction of maxillary canine were selected. All patients were treated by closed-flap surgery with ultrasonic instruments. Periodontal status was evaluated by assessing probing depth (PD), gingival recession and width of keratinized tissue (KT) 4.6 months after the end of the orthodontic treatment, on average. Test group was composed by impacted elements and adjacent teeth and control group by contralateral spontaneously erupted canines and adjacent teeth. Student's t-test was used to compare test and control group values of PD and width of KT. Significance threshold for Student's t-test was set at p < 0.05. The average probing depth values show no significant clinical differences between the test and control groups. Probing depths recorded at the mesiovestibular and distopalatal sides of the impacted canine were statistically significant compared to the control elements (p < 0.05). No gingival recession was detected on the treated canines. The measurement of KT did not differ significantly between the test and the control groups. In conclusion, the ultrasonic surgery for disinclusion associated with a closed approach and orthodontic traction allows the alignment of an impacted palatal canine without damaging the periodontium.
