Within the limitation of this review and based on previous studies, implant restoration has a noticeable residual alveolar ridge preservation which varies from reducing rate of physiologic resorption to bone apposition. However, the extension of this preservation from the implant to surrounding bony area, horizontally and vertically, is unknown. So, further studies are needed to elaborate the exte...
As most of the previous studies declared the favorable bone preservation of the residual alveolar ridge anteriorly around implants, biomechanically, and according to finite element analysis, bone modifying shows variations depending on the cancellous or cortical nature. Bone density is enhanced gradually from the third month to the end of the first year of loading coming stable after 30 months. W...
Despite age-related [71], local and/or systemic factors causing prolonged ridge resorption [9], authors reported the probability of preservative effect and overhaul to maintain the residual alveolar ridge with different restoration [70, 71]. In the previous study, bone formation was noticed with the distal implant in severely resorbed atrophied mandibular ridge [20]. Sennerby et al. [72] concluded...
Many procedures are used to recover denture foundation, but the majority is considered sophisticated techniques [51–53]. Observations tried to notify bone modifications with different types of implant-assisted restoration [23, 40, 54]. The clinical and radiographic investigations, detection of the altered mineral levels, or bone density within the bone may give a valuable data for the bony state...
Bone changes were reported after implant placement in three phases: healing, remodeling, and equilibrium. The remodeling phase is launched confronting the altered pattern of force transmission to the bone tissue. To withstand the applied functional load, continuous remodeling is conducted to reach a “steady state.” Mechanical stimulus is the primary bone modifier influenced by other in situ va...
Apparently, there is an enduring adaptive process surrounding the implant which sustains the rigid interface between alveolar bone and implant after non-destructive surgical and loading procedures. Like other body bones, and according to Wolff’s law, bone has the ability to differentiate with different stresses applied [22]. This reform is started from the time of surgical conduction of implant ...
The required documents were collected from PubMed, Web of Science, and Ovid databases. For expanding the traces of researching, further readings for the bibliography of the relevant publications and hand searching for some denoted articles were done. The keywords, for intervention and outcome, used in research engines in databases as “implant overdenture,” “implant bone resorption,” “alv...
Edentulism is rated between 7 and 69% internationally [1]. Many biological and non-bilogical predisposing factors lead to the main result of edentulism [2]. Regardless the debate to understand the way of resorption [3], the loss of periodontal ligament by tooth extraction leaves alveolar bone without a chance of reformation which leads to bone resorption only. The resorption shows variation in rat...
It has been reported that the load for (or to) implant-supported restoration may lead to bone remodeling as bone resorption and/or formation. While many authors supported the process of bone resorption, others elaborated bone apposition and increasing bone density close and remote to implant body (or fixture). This may suggest the role of the implant to reserve alveolar ridge from physiologic/path...
Figure 45. Radiographic height reduction
The mean crestal height change as assessed on the radiographs was 1.53 mm.
Figure 44. Mean height reduction
The mean reduction in height was approximately 1.7 mm.
Figure 43. Mean width reduction
The weighted means showed that the clinical loss in width is greater than the loss in height. The mean reduction in width of the alveolar ridge was calculated to be approximately 4 mm.
Figure 42. Dimensional change in alveolar bone
A recent systematic review evaluated the amount of change in height and width of the residual ridge after tooth extraction.
Figure 20. Ridge of edentulous site
The outer walls of the alveolar ridge consist of cortical bone. The buccal bone plate is comparatively thinner than the lingual or palatal plate. The cortical plates enclose trabecular bone that consists of bony trabeculae and marrow. As a rule, the ridge of an edentulous site in the maxilla contains comparatively more trabecular bone than a site in the man...
Figure 19. Bone resorption forms alveolar ridge
The term alveolar ridge refers to the alveolar bone following loss of teeth. After a tooth is extracted, the alveolar process heals with formation of bone within the socket and external resorption or shrinkage of the bone, forming the alveolar ridge.
Figure 14. Cortical bone
The cortical bone is comprised of functional units called osteons that consist of concentric lamellae and canaliculi surrounding a central Haversian canal.
Figure 13. Cortical plate
The cortical plates of the supporting bone are continuous with the alveolar bone proper lining the tooth sockets. The cortical plates are thicker in the mandible than in the maxilla, and they are thickest in the molar and premolar regions of the mandible.
Figure 10. Alveolar bone proper
The gross anatomic term is alveolar bone proper, which is synonymous with the term cribriform plate, so-called because it is perforated by many minute openings for vascular and nervous components.
Figure 9. Alveolar bone proper
The histologic term for alveolar bone proper is bundle bone. In histologic sections, the alveolar bone proper appears as a thin lamella of cortical bone lined with bundle bone. Extrinsic collagen fiber bundles of the periodontal ligament known as Sharpey's fibers are embedded into the bundle bone. Their purpose is to connect the bundle bone with the root cementu...
Figure 11. Attachment apparatus
As shown in this histologic section, bundle bone, periodontal ligament, and cementum form an anatomic unit. When a tooth is extracted, the cementum and much of the periodontal ligament are removed. The bundle bone resorbs after tooth extraction.
Figure 9. Lamina dura
The radiographic term for alveolar bone proper is lamina dura. This structure appears more dense than adjacent bone on radiographs. Widening or disruption of the lamina dura may indicate periodontal pathology.
Figure 8. Different terms for the alveolar bone proper
There are several different terms used to describe the alveolar bone proper.
The gross anatomic term is alveolar bone proper, which is synonymous with the term cribriform plate, so-called because it is perforated by many minute openings for vascular and nervous components.
The histologic term is bundle bone. In histologic sections, the ...
