“…[13][14][15] Although many recent studies draw this same conclusion, these previous studies combine sexes for analysis, or do not differentiate between younger and older subjects. [16][17][18][19][20][21][22] The focus of this study is on sex-related and age-related differences, and hence uses an adequate sample size to identify differences between younger and older subjects of each sex.…”

“…Buccal and palatal bone thickness of maxillary central and lateral incisors has been evaluated with CBCT by many researchers [15-17]. Maxillary premolar region is also important for esthetics but relatively few studies have been conducted for the premolar region [15].…”

PurposeThe main purpose of this study was to investigate bone thickness on the buccal and palatal aspects of the maxillary canine and premolars using cone-beam computed tomography (CBCT). The differences between left- and right-side measurements and between males and females were also analyzed.MethodsThe sample consisted of 20 subjects (9 males and 11 females; mean age, 21.9±3.0) selected from the normal occlusion sample data in the Department of Orthodontics, The Catholic University of Korea. The thickness of the buccal and palatal bone walls, perpendicular to the long axis of the root were evaluated at 3 mm and 5 mm apical to cemento-enamel junction (CEJ) and at root apex.ResultsAt the canines and first premolars regions, mean buccal bone thickness of at 3 mm and 5 mm apical to CEJ were less than 2 mm. In contrast, at the second premolar region, mean buccal bone thickness at 3 mm and 5 mm apical from CEJ were greater than 2 mm. Frequency of thick bone wall (≥2 mm) increased from the canine to the second premolar.ConclusionsThis result should be considered before tooth extraction and planning of rehabilitation in the canine and premolar area of maxilla. Careful preoperative analysis with CBCT may be beneficial to assess local risk factors and to achieve high predictability of success in implant therapy.

“…In some reports, the buccal bone crest was used as a reference point. 18,19 Other studies used the CEJ as a reference point, and measurements were taken at points 1 to 5 mm from the buccal bone crest. 14,20,21 In this study, bone thickness was measured starting at 3 mm from the CEJ because implants have been suggested to be placed apico-coronally, 2 to 3 mm below the adjacent CEJ.…”

This study presented the thickness of the buccal and lingual bone in different locations apical to the CEJ in subjects with normal occlusion and the frequency distribution of thick buccal bone wall (≥ 2 mm). The second premolar had the highest frequency distribution of thick buccal bone (≥ 2 mm) when compared with canine and the first premolar. The teeth with thin buccal bone (< 2 mm) should be treated with care for the implant because a thin buccal bone may be damaged more easily and buccal bone resorption may occur. This study may provide estimated value for patients with normal occlusion during tooth extraction and implant installation in the canine and premolar area of the mandible. Preoperative radiographic analysis, with care in using CBCT, may be applied for tooth extraction and implant therapy.

The Thickness of Facial Alveolar Bone Overlying Healthy Maxillary Anterior Teeth

Abstract: The present study supports the finding of a predominantly thin facial bone overlying the six maxillary anterior teeth. Therefore, it is essential to make informed treatment decisions based on thorough site evaluation before immediate implant placement.
