One-piece implants: Careful approach for complex rehabilitation

The Heath of The Peri-Implant Phenotype after Immediate Insertion and Loading of One-Piece and Two-Piece Dental Implants in the Anterior Region. A Clinical and Cone-Beam Computed Tomographic Study

“…All implants presented enough peri-implant keratinized soft tissue, low rates of probing depth (mean 2.25 mm), and the presence of the preimplant bone level was stable, with a mean bone loss over 2 years after loading of 0.83 mm. 13 When comparing the present results to those from a prior study, the change in bone height of two-piece was 0.2 ± 0.08 and in one piece it was −1.41 ± 0.8 over the observation period. Both studies, with different placement modalities and protocols, showed comparable outcomes.…”

“…10 12 One-piece implants were developed to incorporate the transmucosal abutment as an integral part of the implant and thus eliminate the structural weakness built into two-piece implants. 13 One-piece implants have many advantages, including strong unibody design, no split components, single-stage surgery with either a flap or flapless approach, and simple restorative techniques. Absence of micro gap, micro infiltration, absence of pumping effect, 14 use of small diameter prosthetics, and laboratory simplification could enhance the health and maturation of soft tissues during the healing phase and provide economic sustainability.…”

“…Absence of micro gap, micro infiltration, absence of pumping effect, 14 use of small diameter prosthetics, and laboratory simplification could enhance the health and maturation of soft tissues during the healing phase and provide economic sustainability. 13,15 The absence of an implant/abutment interface microcap at the bone crest in one-piece implants was associated with reduced peri-implant inflammatory cell accumulation and minimal bone loss. 16 The long-term preservation of crestal bone height around osseo-integrated implants is often used as a primary success criterion for different implant systems.…”

Bone loss and prosthetic complications with short and narrow diameter implants used to retain mandibular implant overdentures: A Randomized Clinical Trial.

“…The immediate loading protocol was followed in this study, as the results of several other studies revealed no significant difference between immediate and delayed implant loading. 24,25 One-piece implant systems were used to diminish crestal bone loss based on the theory that contamination of the implant-abutment junction or the micro-gap, and violation of the biological width are the originators of the initial bone loss in two-piece implants, 26 that is why one-piece implants were used in this study.…”
