Success rate of dental implants inserted in horizontal and vertical guided bone regenerated areas: a systematic review

Angulated Implants: An Alternative to Bone Augmentation and Sinus Lift Procedure: Systematic Review

“…But scenario is different in case of angulated implants. The angulated implants direct the forces at an angle and thus are associated with higher forces acting on implant bone interface during axial loading [24] which should logically induce bone resorption by disrupting bone implant interface which is supported by in vitro experiments that show that non axial loads cause stress concentration in the marginal area of bone [38][39][40][41] but this hasn't been demonstrated in vivo or in other words crestal bone around neck of an implant but this doesn't happen because all prostheses fabricated on implants placed using this technique are removable type and produces intermittent type of force on implants in contrary to fixed prosthesis. But, one study has showed excellent outcome with immediately loaded fixed full prosthesis [19].…”

“…One review revealed that there are not many studies providing data on success rate of dental implants placed in onlay graft augmented ridges and demonstrated, on average, a poor methodological quality [40].…”

Regeneração tecidual guiada em implantodontia: Relato de caso clínico

“…De modo geral, o resultado funcional obtido na substituição de dentes perdidos tem sido excelente principalmente em áreas em encontramos uma quantidade/qualidade de osso suficiente para que exista uma adequada estabilidade primária do implante 13 . Porém, em nosso caso clínico podemos observar uma falha óssea depois da instalação do implante, sendo que esta já é esperada e por alguns motivos como, por exemplo, a falta de osso vestíbulo-lingual devido à reabsorção óssea após a perda do elemento dental 14 . Por isso foi utilizado um implante com uma geometria mais favorável, nesse caso, o implante Cone Morse, que apresenta um papel relevante em preservação de tecido ósseo, uma vez que permite uma taxa menor de perda óssea quando comparado com outros modelos de implantes 9 , como, por exemplo, de hexágono externo.…”

Application of interconnected porous hydroxyapatite ceramic block for onlay block bone grafting in implant treatment: A case report (Review)

“…Autogenous onlay block bone grafts are widely used for external augmentation in cases of horizontal and vertical alveolar ridge atrophy, as placement on the surface of the host bone can restore bone volume (2,3). Furthermore, several reports have noted that implant treatment with an autogenous onlay block bone graft for horizontal or vertical alveolar ridge atrophy results in bone gain and high rates of implant success (3)(4)(5)(6). However, autogenous block bone grafting also has some disadvantages, such as limited availability of grafts with sufficient size and shape, and risk of donor site morbidity, including long-lasting pain, fracture, and nerve damage (7)(8)(9).…”
