Histologic and radiographic observations suggest that a biologic dimension of hard and soft tissues exists around dental implants and extends apically from the implant-abutment interface. Radiographic evidence of the development of the biologic dimension can be demonstrated by the vertical repositioning of crestal bone and the subsequent soft tissue attachment to the implant that occurs when an implant is uncovered and exposed to the oral environment and matching-diameter restorative components… Expand

Platform Switching - A Review
Histological and radiological observations suggest that a biological dimension of hard and soft tissues exist around the dental implant and extends apically from the implant-abutment interface. AfterExpand
Peri-implant bone level around implants with platform-switched abutments: preliminary data from a prospective study.
TLDR
This clinical trial showed that crestal bone height around dental implants could be influenced using a platform switch protocol and that the bone level would remain stable within 1 year after final prosthetic reconstruction and appears to preserve peri-implant bone levels. Expand
Effects of a new implant abutment design on peri-implant soft tissues.
TLDR
The results suggest that the modified groove design incorporated in standard abutments confers both soft and hard tissue benefits. Expand
Soft and hard tissue histologic dimensions around dental implants in the canine restored with smaller-diameter abutments: a paradigm shift in peri-implant biology.
TLDR
This study reveals a fundamental change in the biologic response to implants with nonmatching implant-abutment diameters and suggests that marginal inflammation is eliminated or greatly reduced in these implant designs. Expand
Immediate Provisionalization on a New Implant Design for Esthetic Restoration and Preserving Crestal Bone
TLDR
An implant design that incorporates the concept of platform switching is a simple and effective way to control circumferential bone loss around dental implants, helping to ensure a predictable esthetic result. Expand
Immediate provisionalization on a new implant design for esthetic restoration and preserving crestal bone.
TLDR
An implant design that incorporates the concept of platform switching is a simple and effective way to control circumferential bone loss around dental implants, helping to ensure a predictable esthetic result. Expand
Bone response to loaded implants with non-matching implant-abutment diameters in the canine mandible.
TLDR
Minimal histologic bone loss occurred when dental implants with non-matching implant-abutment diameters were placed at the bone crest and were loaded for 6 months in the canine. Expand
Histology of a dental implant with a platform switched implant-abutment connection
TLDR
A histologic analysis of an implant with a platform switched implant-abutment connection with a 32-year-old male patient who needed a bilateral mandibular restoration found platform- switching could help in maintaining the height of the peri-implant crestal bone. Expand
Peri‐implant tissue healing at implants with different designs and placement protocols: An experimental study in dogs
TLDR
Bone remodeling occurred within the early healing phase at subcrestal or crestal placement of implants with or without "platform-switched" implant/abutment connections, with significantly less crestal bone loss compared to PM. Expand
New Generation of Fixture–Abutment Connection Combining Soft Tissue Design and Vertical Screw-Retained Restoration: 1-Year Clinical, Aesthetics and Radiographic Preliminary Evaluation
TLDR
Implant design factors and the abutment connection are correlated with crestal bone stability, and these factors seem to be a viable treatment option for the rehabilitation of a single tooth gap within the limitations of the present study. Expand

Biologic Width around one- and two-piece titanium implants.
TLDR
Findings, as evaluated by nondecalcified histology under unloaded conditions in the canine mandible, suggest that the gingival margin (GM) is located more coronally and Biologic Width (BW) dimensions are more similar to natural teeth around one-piece nonsubmerged implants compared to either two- piece nonsubMERged or two-piece submerged implants. Expand
Influence of the microgap in the peri-implant hard and soft tissues: a histomorphometric study in dogs.
TLDR
There was a clear tendency of the epithelium and connective tissue to be longer the deeper the implants were placed, although those differences were not statistically significant. Expand
Role of the microgap between implant and abutment: a retrospective histologic evaluation in monkeys.
TLDR
The results confirm data published previously that if the microgap was moved coronally away from the alveolar crest, less bone loss would occur andIf the micro gap was moved apical to theAlveolars crest, greater amounts of bone resorption were present. Expand
Crestal bone changes around titanium implants: a methodologic study comparing linear radiographic with histometric measurements.
TLDR
Standardized periapical radiography can evaluate crestal bone levels around implants clinically accurately in a high percentage of cases and may prove beneficial when trying to distinguish physiologic changes from pathologic changes or when Trying to determine causes and effects of bone changes around dental implants. Expand
Crestal bone changes around titanium implants. A radiographic evaluation of unloaded nonsubmerged and submerged implants in the canine mandible.
TLDR
It is demonstrated that the rough/smooth implant interface as well as the location of the microgap have a significant effect on marginal bone formation as evaluated by standardized longitudinal radiography. Expand
Crestal bone changes around titanium implants. A histometric evaluation of unloaded non-submerged and submerged implants in the canine mandible.
TLDR
These findings, as evaluated by non-decalcified histology under unloaded conditions, demonstrate that crestal bone changes occur during the early phase of healing after implant placement, and are dependent on the surface characteristics of the implant and the presence/absence of an interface. Expand
Dental implant design--effect on bone remodeling.
TLDR
Bone remodeling around three different endosseous dental implant designs placed in dog mandibles was studied using radiography during lengthy periods of function and by histology after animal sacrifice, indicating that some crestal bone loss occurred for both the threaded and partially porous-coated implants. Expand
Influence of the size of the microgap on crestal bone changes around titanium implants. A histometric evaluation of unloaded non-submerged implants in the canine mandible.
TLDR
These findings demonstrate, as evaluated by non-decalcified histology under unloaded conditions in the canine mandible, that crestal bone changes around 2-piece, non-submerged titanium implants are significantly influenced by possible movements between implants and abutments, but not by the size of the microgap (interface). Expand
Soft tissue response to plaque formation at different implant systems. A comparative study in the dog.
TLDR
It is demonstrated that plaque formation resulted in the establishment of an ICT lateral to a pocket epithelium in the peri-implant mucosa of the 3 implant systems tested. Expand
The long-term efficacy of currently used dental implants: a review and proposed criteria of success.
TLDR
Criteria for the evaluation of dental implant success are proposed and an attempt has been made to standardize the basis for comments on each type of implant. Expand
