“…Rojo-Sanchis et al [44] substantiate an inverse relationship between the CEJ-BC distance and alveolar BCT through their tomographic study. Meanwhile, in this study, a reduction in the mean maxillary BCT in the case group was observed, compared with controls but not to a statistically significant degree.…”

This research aims to investigate the relationship between orthodontic treatment (OT) and altered passive eruption (APE). Materials and Methods: A case–control study was carried out among the dentistry students at Jazan University. A total of 21 students were recruited for the case group and 20 others for the control group. Variables were measured on the maxillary incisor teeth. They included an image analysis of the teeth width-to-height (W/H) ratio, a cone beam computed tomography (CBCT) analysis of buccal bone thickness (BCT), and the distance from the cementoenamel junction (CEJ) to the bone crest (BC) (CEJ–BC). In addition, a systematic review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Prominent literature databases, including Medline/PubMed, the Cochrane Library, Embase, Scopus, Saudi Digital Library, and Google Scholar, were searched for articles published before November 2022 on two main concepts (APE and orthodontics). Quality of evidence was assessed using the Newcastle–Ottawa scale (NOS), and the certainty of evidence was assessed using the grading of recommendations assessment development and evaluation (GRADE) approach. Results: A total of 164 teeth were evaluated. No statistical differences were observed in the W/H ratio and BCT between the two groups. A significant increase in the CEJ–BC distance in the right and left maxillary lateral incisors was observed for people who had undergone OT (p ≤ 0.002 and 0.001, respectively). In the systematic review, two articles were included for qualitative synthesis. One of the included studies showed an increase in the post-orthodontics clinical crown length of the maxillary anterior teeth. Another study reported no difference in the prevalence of APE between orthodontically treated and untreated people. Conclusion: This research concludes that OT might not be an etiological factor for APE. However, more clinical and radiological studies must be conducted to arrive at decisive conclusions.

Background Traditional protocols for implant surgery suggest a healing period of 2-3 months from dental extraction to implant placement. Based on all the volumetric modifications produced by that approach, there are authors who advocate for immediate implantology. The aim of the present study was to determine the prevalence of different sockets, and the dimensions of the bone around the upper anterior incisors and canines, to determine the predictability of immediate implants in our population. Material and Methods This is an observational, cross-sectional study based on cone-beam computed tomography images of the anterior maxila of patients attending the Odontological Hospital of the University of Barcelona (OHUB) and requesting for implant treatment. Different measurements were performed on every analyzed tooth, and also they were categorized by using the main dental sockets classifications. Results Bone attachment levels and cortical thickness are lower in women compared to men in all three types of teeth (the difference in the bone attachment levels ranges from 4.68%-8.63% and in the bone thickness goes from 0.02-0.58mm). Bone attachment level gradually reduces with age. The reductions observed in all the measurements are higher in the case of canines, compared with the other teeth. The differences from patients <45 years old and patients between 55-64 years old are 13.58±14.55mm in the case of central incisors, 10.04±5.52 in the case of lateral incisors and 22.39±13.65mm in the case of canines. Conclusions According to our results, the canines are the teeth with the greatest complexity when it comes to immediate implantology treatments. Furthermore, that kind of treatment is more complex as age increases, since we observed a gradual percentage of unfavourable sockets in older patients. Key words: Bone attachment, cortical bone height, cortical thickness, bone resorption, type of socket, immediate implants.

“…Progressive periodontal attachment loss throughout life also results in an increased CEJ-FBC distance [ 16 ]. A recent study has published an inverse relationship between CEJ-FBC distance and FAB thickness at anterior maxillary teeth [ 54 ]. Even some authors have also associated shorter CEJ-FBC distances with thicker gingival biotype [ 44 , 45 ].…”

Facial alveolar bone thickness and modifying factors of anterior maxillary teeth: a systematic review and meta-analysis of cone-beam computed tomography studies

Background Understanding the anatomy of the facial alveolar bone (FAB), provides a prognostic tool for estimating the degree of dimensional ridge alterations after tooth extraction. This systematic review and meta-analysis aims to determine the FAB thickness and modifying factors of anterior maxillary teeth measured by CBCT scans. A secondary objective was to assess the facial distance from the cementoenamel junction (CEJ) to the bone crest. Methods An electronic search was made of Medline, Embase, Web of Science, Cochrane Library and Google Scholar up to December 2019. Studies that analyze and quantitatively compare FAB thickness at maxillary teeth by CBCT scans were included. The methodological quality of the included studies was appraised using the ROBINS-I tool and the overall meta-evidence certainty using the GRADE approach. A single means random-effects meta-analysis was performed to obtain the weighted mean for 95% confidence interval. A meta-regression of covariates and subgroup analysis was conducted. The nullity Qh test and I2 index for heterogeneity was estimated. Results 2560 potentially relevant articles were recorded from which 29 studies were selected for the qualitative analysis, including 17,321 teeth. Seventeen studies considered the facial bone crest, and 12 the CEJ as a reference point for their measurements. Mean FAB thickness was ≤ 1 mm in maxillary incisors and canines (0.75–1.05 mm) and 1–2 mm in premolars. Patients over 50 years of age, females and thin gingival phenotype was associated with thinner FAB at some apico-coronal locations of maxillary incisors and canines. The geographical setting was an effect modifier that could explain up to 87% of the heterogeneity in FAB thickness, being Asian populations that showed the lowest FAB thickness values. The CEJ-bone crest distance was 2–2.5 mm in all teeth analyzed. Population over 50 years of age exhibited greater CEJ-bone crest distances, and males also showed a trend for greater distance. Evidence certainty has shown moderate quality in most analysis subsets. Conclusions Facial alveolar bone at anterior maxillary teeth is thin, heterogeneous in width along its apico-coronal dimensions, and increases in thickness in maxillary premolars. The CEJ-bone crest distance presented homogeneous and similar values in all teeth analyzed.
