Measuring the Facial Plate of Bone in the Upper Anterior Teeth Utilizing Cone Beam Computed Tomography at King Abdulaziz University, Jeddah, Saudi Arabia

Abstract

Background and aimRadiographic assessment is an important diagnostic tool in dental practice. Cone beam computed tomography (CBCT) is among the most important imaging examinations. By providing multiplanar visualization of the maxillofacial region, CBCT enables practitioners to assess various conditions threedimensionally. CBCT is utilized in different fields within dentistry, including oral and maxillofacial surgery, endodontics, orthodontics, periodontics, implant dentistry, and others. Having access to accurate 3D images is crucial in implant dentistry. This study aimed to measure the crestal bone height loss and facial alveolar bone thickness in the maxillary anterior teeth using CBCT to investigate its effect on surgical planning for dental implant placement in adult patients. Material and methodsCBCT scans (N = 119) of adults, aged 18-65 years, with bilateral permanent maxillary anterior teeth present were included in this retrospective study. The mean alveolar bone plate thickness and crest bone height loss adjacent to the maxillary anterior teeth were measured and differences were examined. ResultsThe results suggest that additional care and assessment of dental implant placement should be considered when replacing the permanent lateral incisors and canines. The frequency of fenestrations and dehiscence is higher in older adults. Possible management includes guided bone regeneration or "pink restorative solutions." ConclusionCBCT analysis to assess the bone morphology surrounding "hopeless" maxillary anterior teeth is important to ensure proper diagnosis and management, including the use of dental implants.

A CBCT Study of Labial Alveolar Bone Thickness in the Maxillary Anterior Region in a Teaching Hospital Population in the Eastern Province of Saudi Arabia

“…In all measured points, we have found the bone thickness was less than 2 mm and, in some areas, it was less than 1 mm. These findings of our study were in accordance with the result of Sheerah et al [ 15 ] and Othman et al [ 14 ]. In both of these studies, they measured the mean alveolar bone thickness and reported that, in most cases, the bone thickness was less than 1.5 mm.…”

“…To date, there have been seven studies which have been conducted and have reported facial bone thickness in the Kingdom of Saudi Arabia. Few studies have considered all the six anterior teeth, and some of them considered only a single tooth, such as the canine [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Although there was some similarity in the results among these studies in the data obtained (bone thickness in a particular tooth or alveolar crestal bone height), still, there were differences, and varied findings have been observed.…”

“…Thus, the anatomical importance of this region has drawn the attention of clinicians and researchers to conduct studies to assess facial bony thickness [ 7 , 8 , 9 , 10 , 11 ]. In the Kingdom of Saudi Arabia, several studies are being conducted in different parts of the country [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. The outcome of this study showed variation in the results among the gender, age group, right and left side, and for different teeth.…”

Cone Beam Computed Tomography (CBCT) Evaluation of Alveolar Bone Thickness and Root Angulation in Anterior Maxilla for Planning Immediate Implant Placement

“…The mean thickness of the buccal alveolar bone at the L2 for central incisors, lateral incisors, and canine were (1.06, 0.96, and 0.95 mm) respectively. These values are consistent with the study by AlAli et al (1.17, 0.80, and 0.81 mm) [ 11 ], Othman et al (0.81, 0.68, and 0.71 mm) [ 12 ], Sheerah et al (0.96, 0.92, and 0.84 mm) [ 13 ], Han and Jung (1.25, 0.85, and 1.42 mm) [ 14 ]. The mean thickness of the buccal alveolar bone at the L3 for central incisors, lateral incisors, and canine were (1.89, 1.85, and 1.93 mm) respectively.…”

“…subjects [14 degrees, 95% CI(11)(12)(13)(14)(15)(16)(17)]. The mean lateral incisor height in female subjects[17.6 mm, 95% CI (16.8-18.4)] was statistically significantly different from the male subjects [19.3 mm, 95% CI (18.5-20.1)] (Table3).…”
