Alveolar ridge

The alveolar ridge is an extension of the maxilla the upper part of the jaw and the alveolar ridge the lower part of the jaw and is a bony ridge that holds the sockets of the teeth. The alveolar ridge is a critical anatomical structure for healthy teeth and successful dental implants, alveolar ridge. When a tooth is extracted from the maxillary alveolar ridge or the lower alveolar ridge, bone loss typically occurs, alveolar ridge. Without enough dense bone in the alveolar ridge, placing implant hardware can be a challenge.

Federal government websites often end in. The site is secure. The loss of thickness and height of the alveolar process after tooth extraction is a significant impediment to implant placement, which limits the aesthetic results of many restorative treatments. Alveolar ridge preservation can reduce bone resorption. Knowing how beneficial this procedure is can help clinicians decide if it is worth doing. The purpose of this article is to present a contemporary review of the different approaches to preserving the dimensions of the alveolar ridge.

Alveolar ridge

The synonymous terms alveolar ridge [3] and alveolar margin are also sometimes used more specifically to refer to the ridges on the inside of the mouth which can be felt with the tongue , either on roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth. The connected, supporting area of the jaw delineated by the apexes of the roots of the teeth is known as the basal bone. On the maxilla , the alveolar process is a ridge on the inferior surface, making up the thickest part of the bone. On the mandible it is a ridge on the superior surface. The structures hold the teeth and are encased by gums as part of the oral cavity. The alveolar process proper encases the tooth sockets, and contains a lining of compact bone around the roots of the teeth, called the lamina dura. The alveolar bone proper is also called bundle bone because Sharpey's fibres , part of the PDL, are inserted there. Sharpey's fibres in alveolar bone proper are inserted at a right angle just as with the cemental surface ; they are fewer in number, but thicker in diameter than those found in cementum. The supporting alveolar bone consists of both cortical compact bone and trabecular bone. The cortical bone consists of plates on the facial and lingual surfaces of the alveolar bone. These cortical plates are usually about 1. The alveolar structure is a dynamic tissue which provides the jawbone with some degree of flexibility and resilience for the embedded teeth as they encounter numerous multi-directional forces. The mineral salts it contains are mostly in the form of calcium hydroxyapatite crystals. The cellular component of bone consists of osteoblasts , osteocytes and osteoclasts. Bone is lost through the process of resorption which involves osteoclasts breaking down the hard tissue of bone.

Alveolar ridge preservation ARP is a method of decreasing bone resorption following tooth extraction and facilitating prosthetically-driven implant placement. An understanding of the physiological responses occurring after extraction and the effects of ARP are important in order to implement clinical procedures.

Numerous randomised controlled trials have compared alveolar ridge preservation to extraction alone. A recent Cochrane review reported that, in terms of socket dimensional change, the mean difference between alveolar ridge preservation and extraction alone is 1. The clinical impact of this is uncertain, for there is no significant difference in the need for graft procedures at implant placement between ridge preservation and extraction alone. There are no randomised controlled trials comparing aesthetic or functional outcomes. A systematic review of the histological outcomes of ridge preservation demonstrates that, compared to extraction alone, many bone substitute materials can significantly delay the bone healing process.

Objective: The aim of this in vivo study is to compare the osseointegration of endosteal implants placed in atrophic mandibular alveolar ridges with alveolar ridge expansion surgical protocol via an experimental osseodensification drilling versus conventional osteotome technique. After 4 weeks of healing, samples were retrieved and stained with Stevenel's Blue and Van Gieson's Picro Fuschin for histologic evaluation. A significant omnibus test, post-hoc comparison of the 2 drilling techniques' mean values was accomplished using a pooled estimate of the standard error with P-value set at 0. Conclusion: The combined osseodensification drilling-alveolar ridge expansion technique showed increased evidence of osseointegration and implant primary stability from a histologic and biomechanical standpoint, respectively. Future studies will focus on expanding the sample size as well as the timeline of the study to allow investigation of long-term prognosis of this novel technique.

Int J Oral Maxillofac Implants ; Translations of alveolar ridge in Chinese Traditional. It has been reported that the effect of raising a flap on bone resorption remains unclear, however other studies have shown that the elevation of a full thickness flap can cause resorption of thin bone walls.
