The purpose of this study was to analyze the thickness of the facial alveolar bone at the first and second maxillary premolars and determinate the percentage of premolars that reached 2 mm in width. A retrospective study was performed, analyzing cone beam computed tomography scans from the database of the Oral Surgery Unit of the University of Valencia. Patients with periodontal disease, orthodontic treatment, absence among the first maxillary molars, premolars with endodontic treatment, or prosthetic restorations were excluded. The facial alveolar bone width was measured at 1, 2, 3, and 5 mm apical to the vestibular bone peak. A total of 44 patients were included in the study, with 72 first premolars and 72 second premolars analyzed. A descriptive analysis was performed and the normal means were assessed using the Kolmogorov-Smirnov test. The average width of the facial alveolar bone at first and second maxillary premolars was respectively: 1.41 ± 0.50 and 1.72 ± 0.56 at 1 mm, 1.68 ± 0.72 and 2.23 ± 0.66 at 2 mm, 1.71 ± 0.89 and 2.43 ± 0.82 at 3 mm, 1.44 ± 1.00 and 2.31 ± 1.06 at 5 mm from the vestibular bone peak. The facial alveolar bone width at the second maxillary premolars was greater than at the first maxillary premolars at all points measured. This information should be taken in account when planning immediate implants. Further studies are needed to analyze bone resorption at maxillary premolars to better understand facial alveolar bone width influence in implant treatment.

Abstract Background The aim of the study was to evaluate the anatomical relationship between the maxillary molars and the maxillary sinus by using cone beam computed tomography (CBCT).Methods A database of maxillary molars were obtained from 91 adult patients by means of images of CBCT. The internal angle, the alveolar bone width, and the distance between root apex and the wall of maxillary sinus were measured by CBCT. The vertical relationship between the maxillary molars and the maxillary sinus were analysed. Vertical relationship of the maxillary sinus was further evaluated. Results The value of the internal angle of maxillary third molar is 17.2 ± 11.5°. The width of the alveolar bone of third molar is 8.2 ± 1.7mm. Type III, IV and V were the most common relationship in the first and second molars. Type V and I were most frequently observed in the first and second molars. The inner angle of the second molar is larger than that of the first molar. The maxillary first molar had the smallest mean alveolar bone width, and the third molar had the largest average. Conclusion This study will provide reference for clinical practice, especially for root canal treatment and tooth implants.

ABSTRACT Aim The aim of this study was to analyze bone dimensions of the dentate posterior mandible using cone beam computed tomography (CBCT). Objectives The objectives of this study were • To measure thickness of buccal and lingual bone walls in mandibular posterior teeth using CBCT. • To measure alveolar bone width in mandibular posterior teeth using CBCT. Materials and Methods Ten CBCT scans were included in the study (n = 65 teeth). Thicknesses of buccal and lingual walls were measured at measurement point 1 (MP1) and measurement point 2 (MP2). Alveolar width was assessed at most coronal detected alveolar bone (BW1) and at superior border of mandibular canal (BW2). Vertical distance between BW1 and BW2 was measured (H). Data were tabulated and results were statistically analyzed using unpaired t test. Results The study showed that there was an increase in bone wall thickness from 1st premolar to 2nd molar for buccal and lingual alveolar plates. Lingual bone walls were thicker than buccal bone walls at MP1 and MP2 for all teeth. Bone width for premolars was considerably less than bone width of molars. Conclusion Careful preoperative analysis using CBCT is important to assess need of bone augmentation procedures. As the bone thickness and width in the molar region is more adequate, prognosis of implants placed in molar region may be better. Clinical significance Analysis of bone dimensions is of utmost importance for successful outcome of bone augmentation procedures in implant treatment.

Before And After

The aim of this study was to use a cone-beam computed tomography (CBCT) to assess changes in alveolar bone width around dental implants at native and reconstructed bone sites before and after implant surgery. A total of 99 implant sites from 54 patients with at least two CBCT scans before and after implant surgery during 2010–2019 were assessed in this study. Demographic data, dental treatments and CBCT scans were collected. Horizontal alveolar bone widths around implants at three levels (subcrestal width 1 mm (CW1), subcrestal width 4 mm (CW4), and subcrestal width 7 mm (CW7)) were measured. A p-value of < 0.05 indicated statistically significant differences. The initial bone widths (mean ± standard deviation (SD)) at CW1, CW4, and CW7 were 6.98 ± 2.24, 9.97 ± 2.64, and 11.33 ± 3.00 mm, respectively, and the postsurgery widths were 6.83 ± 2.02, 9.58 ± 2.55, and 11.19 ± 2.90 mm, respectively. The change in bone width was 0.15 ± 1.74 mm at CW1, 0.39 ± 1.12 mm at CW4 (p = 0.0008), and 0.14 ± 1.05 mm at CW7. A statistically significant change in bone width was observed at only the CW4 level. Compared with those at the native bone sites, the changes in bone width around implants at reconstructed sites did not differ significantly. A significant alveolar bone width resorption was found only at the middle third on CBCT scans. No significant changes in bone width around implants were detected between native and reconstructed bone sites.
