Abstract:
Bone modeling and remodeling following tooth extraction has been studied extensively. The reason for bone loss during the remodeling process is multifactorial, and the primary reason for this loss is still yet to be determined. The aim of this study was to examine the type of bone and the blood supply to the buccal bone in monkeys. Six maxillary arches from six monkeys were used. The arches were divided into three sections: right posterior, anterior from canine to canine, and left posterior. Blocks were decalcified and prepared for histologic processing and examination. Modified Masson trichrome and retic staining were used. Histologic sectioning demonstrated that the blood supply to the buccal bone came from the inner (socket) side of the alveolus, the periodontal ligament, the adjacent interdental bone, and the supraperiosteal vessels emanating from the covering gingiva or mucosa. Histologic examination showed that the buccal bone was composed of bundle and cortical bone. The thickness of the buccal bone was not uniform coronoapically, and the thinnest area of buccal bone was the coronal portion.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
