“…The authors observed that a thin buccal bone wall predominated (<1 mm) at the crest (83%) and the mid‐root point (92%) while most palatal walls were thin (<1 mm) at the crest (63%) and thick (≥2 mm) at the mid‐root point (98%) and apex (99%). These findings are in agreement with other studies 63,69,72 . Botelho et al 9 assessed the dimension of the palatal triangle at maxillary anterior teeth.…”

Following tooth extraction, a sequence of events takes place in order to close the wound and restore tissue homeostasis, a process called socket healing. The outcome of socket healing includes a marked reduction of the ridge dimensions. The amount of tissue loss that occurs during healing is influenced by several local and systemic factors. Thus, the aim of the present review was to describe the effect of anatomical characteristics of the alveolar process and basal bone on the socket healing outcome. The studies included showed that the quantity (number) and quality (composition) of socket walls exhibited a significant influence on the ridge diminution. A damaged socket (3 walls or less), as well as a thin buccal bone wall, which quickly resorbs negatively affected the healing outcome. Periodontally compromised sockets appeared to promote more extensive dimensional changes. Angulation between tooth and basal bone in addition to basal bone dimensions may also have altered the wound environment and influenced socket healing. The findings from the present review suggest that some anatomical characteristics of the alveolar process and basal bone have an effect on socket healing.

“…The thickness of the alveolar bone is one of the important factors affecting the long-term stability of the implants. It has been suggested that at least 1 mm or 2 mm of buccal bone not only maintains a stable vertical dimension of the alveolar crest [22] ,but also ensures proper soft tissue support and avoids the risk of peri-implant soft-tissue recession [23] .The present work revealed that 11.47%, 9.95% and 12.29% of central incisor, lateral incisor, and canine buccal bone sites were ≥ 2mm, respectively. Fuentes et al [24] concluded a coinciding view with the present nding.…”

“…Class SRP presented the highest buccal ABT, whereas class presented the lower buccal ABT, and the buccal ABT in class was about 30.71% thinner than in class (0.97 ± 0.82 mm versus 1.40 ± 1.38 mm). Rodrigues et al [23] . had the same nding.…”

Background The aim of this study was to analyze the buccal and palatal alveolar thickness and morphologic features of relatively healthy maxillary anterior teeth using cone-beam computed tomography (CBCT). Methods Buccal and palatal bone thickness at central incisors, lateral incisors and canines was measured at four reference lines on CBCT scans of 1824 Chinese patients (152 males and 152 females). Alveolar bone thickness (ABT), sagittal root position (SRP), the angulation between the axis of the teeth and the alveolar process, and the inclination of the anterior teeth in the alveolar socket were measured using 3-dimensional imaging software. Results The thickness of buccal maxillary anterior alveolar bone thickness was 57.59% less than 1mm, and decreased with age. Bone thickness was greater in males than in females. The buccal and palatal ABT of the central incisors, lateral incisors, and canines were significantly different between males and females. The buccal ABT of females decreased with age. The SRP classification was significantly different in age distribution, regardless of gender. The SRP was significantly correlated with the buccal and palatal ABT in the apex. The angulation between the axis of the teeth and the alveolar process increased with age. The inclination of the anterior teeth in the male was significantly greater than that in the female. Conclusions Preoperative analysis using CBCT may be beneficial for establishing the treatment planning because the buccal and palatal alveolar bone thickness is associated with age and gender, as well as the position relationship between the tooth root and alveolar bone.

“…The morphology of the postextraction site has been reported to define the position of the original root in the alveolar bone, which can provide information that can be used to predict future implant stability. 9,10 Kan et al 9 presented a classification of the sagittal root position (SRP) to assist implant treatment planning, in which the relationship between the root position and its osseous housing is categorized as Class I, II, III, or IV. 10 To acquire reliable information, precise radiographic images, such as those obtained using three-dimensional computed tomography, are necessary.…”

Background: The anatomical characteristics of the maxillary labial alveolar bone play a crucial role in the treatment planning of immediate implant placement. The sagittal root position (SRP) and alveolar bone concavity are closely related to anatomical characteristics in determining the ideal implant position. This study evaluated the SRP and labial alveolar bone concavity in the maxillary anterior teeth area. Methods: Cone-beam computed tomography images of 120 samples involving 720 teeth were uploaded to the medical imaging software. The SRP was classified as Class I, II, III, or IV, and the concavity of labial alveolar bone was measured. A T test was performed to compare measurements between the central and lateral incisors, between the central incisors and canines, and between the lateral incisors and canine. Results: The majority of the SRPs of the maxillary anterior teeth were class I (engaging the labial cortical plate) with frequencies of 98.3%, 85.8%, and 81.7% for the canines, lateral incisors, and central incisors, respectively. In terms of concavity of labial alveolar bone in maxillary tooth area, canines also had the largest mean value (139.5°), followed by lateral incisors, whereas central incisors has the smallest mean value (131.7°). The results of the T test revealed a significant difference (p < 0.001) in labial alveolar bone concavity between central and lateral incisors, between central incisors and canines, and between lateral incisors and canines. Conclusion: Most maxillary anterior teeth were classified as Class I SRP, Class III SRP was the least prevalent, and the concavity of the labial alveolar bone significantly differed between the central and lateral incisors, between the central incisors and canines, and between the lateral incisors and canines. In addition, the canines had the highest mean alveolar bone concavity angle, indicating that less concavity in the canines area.
