Can Male Patient’s Age Affect the Cortical Bone Thickness of Jawbone for Dental Implant Placement? A Cohort Study

Abstract

Dental implants are among the most common treatments for missing teeth. The thickness of the crestal cortical bone at the potential dental implant site is a critical factor affecting the success rate of dental implant surgery. However, previous studies have predominantly focused on female patients, who are at a high risk of osteoporosis, for the discussion of bone quality and quantity at the dental implant site. This study aimed to investigate the effect of male patients’ age on the crestal cortical bone of the jaw at the dental implant site by using dental cone-beam computed tomography (CBCT). This study performed dental CBCT on 84 male patients of various ages to obtain tomograms of 288 dental implant sites at the jawbone (41 sites in the anterior maxilla, 95 in the posterior maxilla, 59 in the anterior mandible, and 93 in the posterior mandible) for measuring the cortical bone thickness. A one-way analysis of variance and Scheffe’s test were performed on the measurement results to compare the cortical bone thickness at implant sites in the four jaw areas. The correlation between male patient age and cortical bone thickness at the dental implant site was determined. The four jaw areas in order of the cortical bone thickness were as follows: posterior mandible (1.07 ± 0.44 mm), anterior mandible (0.99 ± 0.30 mm), anterior maxilla (0.82 ± 0.32 mm), and posterior maxilla (0.71 ± 0.27 mm). Apart from dental implant sites in the anterior and posterior mandibles, no significant correlation was observed between male patients’ age and the cortical bone thickness at the dental implant site.

Marginal bone changes around platform‐switched conical connection implants placed 1 or 2 mm subcrestally: A multicenter crossover randomized controlled trial

“…At prosthesis delivery (T1), mean subcrestal positioning of implant platform was 1.49 ± 0.47 mm in Test group and 0.79 ± 0.44 mm in Control group. Considering mean cortical thickness in human jaws (1.07 ± 0.44 mm in the posterior mandible and 0.71 ± 0.27 mm in the posterior maxilla 56 ), at T1 the implant‐abutment junction was likely positioned at cortical level in Control group and subcortically in Test group. Finite element analyses showed that subcrestal placement decreases stress in the crestal cortical bone 57 .…”

“…Understanding them thoroughly requires explaining the relationship between their functions and forms. Skull bone thickness differs between the genders [3,4]. Generally, a female skeleton tends to be smaller and less durable than a male skeleton.…”
