BACKGROUND: A current implant body surface was treated with "rough processing" by sandblasting and acid etching for the purposes of obtaining more reliable osseointegration and shortening the treatment period. Various reports have examined the healing period with the use of these implant bodies, but a consensus opinion has not yet been obtained. The purpose of this study is to evaluate the relationship between insertion torque (IT) and implant stability quotient (ISQ) at implant treatment using the current rough-surfaced implant...

OBJECTIVE: In the anterior regions, the resorption of the buccal bone after tooth extraction leads to a contraction of the overlying soft tissues, resulting in an esthetic problem, particularly with immediate implant placement. In the socket shield technique, the buccal root section of the tooth is maintained, to preserve the buccal bone for immediate implant placement. The aim of this prospective study was to investigate the survival, stability, and complication rates of implants placed using a "modified" socket shield technique...

BACKGROUND: Successful dental implant treatment is directly related to osseointegration. In achieving osseointegration, the surface property of the implant is of great importance. Sandblasting is the most commonly used basic method for modifying the surface. Many companies use different sand particles for surface roughening and claim their sand is the best. This leads clinicians to mix their minds in product selection. In this study, we tried to find the appropriate sand material by working objectively without praising any brand...

BACKGROUND: Numerous studies indicate implants placed immediately after extraction or with minimally invasive procedures have excellent long-term success and survival rates. There is general agreement that implants must be stable after implant placement. This study evaluated implant stability changes from the time of implant placement to second stage (prior to restoration). Resonance frequency analysis (RFA) was determined for two commercially available units (Osstell, Osstell USA, Columbia, MD and Penguin, Penguin Integration Diagnostics, Sweden)...

Immediate implants are a valuable treatment option to replace natural teeth in the aesthetic region. The hypothesis of this randomized controlled clinical trial was that immediate implants grafted with autologous platelet-rich fibrin (PRF) have better clinical and radiographic outcomes than non-grafted controls. Forty-one implants were placed in 31 subjects with one or more non-restorable single-rooted teeth. Autologous PRF was placed in the peri-implant region of the study group (n=21) and no augmentation was done in the control group (n=20)...

This study aimed to compare the primary and secondary stability, measured by resonance frequency analysis (RFA), in implants of different lengths installed in areas submitted to maxillary sinus lift. Correlation between RFA and implant insertion torque was also assessed. Twenty implants of 9 and 11 mm were inserted in areas submitted to maxillary sinus lift. The insertion torque was measured by the Bien Air motor. Osstell, through RFA, determined the implant stability quotient (ISQ) 2 times: the day of implant installation (T1) and 90 days after implant installation (T2)...
