The survival of the endosseous implant is highly dependent on the integration between the implant surface and the oral tissue which includes both hard and soft tissues. The first and main sign of rupture loss at the tissue interface of the implant is usually seen in the crestal region. Therefore, crestal bone loss around the implant plays a very important role in determining the success of the osseointegrated implant. Crestal bone loss from the implant during healing and therefore after the first year of operation is often greater during the initial phase. Say no to plagiarism.

We observe that the density of the alveolar bone housing can influence early bone loss around the implants. Studies by Weber et al showed that lower density bones had greater bone loss. According to the assessment of Cook et al, there is a correlation between lip plaque thickness and thin or thick gingival biotypes. Various studies have demonstrated that mucosal thickness and biological width affect crestal bone loss around implants. It is also noted that the dimension and position of the biological width formed around the implant surfaces during the early healing phase can influence the degree of design of the implant ridge module and plays a very crucial role in the formation of a biological seal around the surface of the implant. Platform-Switching is a method used to improve biological sealing and also preserve the crestal bone level around an implant. The concept of Platform Switching was introduced by Lazzara and Porter in 2006. Lazzara et al hypothesized that moving the implant-abutment junction (IAJ) inward also shifts the inflammatory cell infiltrate medially. interior and distance from the crestal bone. Due to the inward horizontal movement of the implant-abutment union, the connective tissue thickens laterally, which increases blood flow around this area. Thus a biological seal is established around the dental implants, these modifications protect the crestal bone. Regarding the biomechanical advantages of using platform switching, unlike conventional implants where a high stress zone around the neck of the implant and along its lateral surface, but in platform switching, stress is distributed inward toward the central axis, thereby improving force distribution and reducing peak marginal bone loss after loading. Berglundh and Lindhe in 1996, in their animal studies, showed that a particular thickness is necessary to establish biological width around the dental implant and they also stated that if less thickness is present, resorption of the crestal bone will occur until sufficient space is established for both connectors. tissue and junctional epithelium. The formation of biological width around an implant is influenced by the gingival biotype. The gingival biotype contributes significantly to the stability of the marginal bone around the dentition/implant. Studies by Becker W et al in 1997 showed that the thin biotype was associated with fenestrations and bone dehiscences. According to Wagenberg B et al and Tabata et al in 2010, the gingival biotype, the distance of the implant-abutment junction (IAJ) from the bone crest, the repositioning of the gingival inflammatory infiltrate and the distribution of forces in the..
