Clinical and Radiographic Evaluation of Crestal Bone Loss Around Implant With or Without Platform Switching Design

Implants have become the preferred method of single tooth replacement these days, patients receiving implant treatments not only expect restoration of masticatory function, they also expect that the prostheses will be esthetically pleasing, easy to clean, and permanent. To maintain long-term implant stability, it is important to minimize bone loss around the implant, as well as the soft tissue atrophy that accompanies it.


The peri-implant bone level has been used as one of the criteria to assess the success of dental implants, Platform switching (PLS) for maintaining peri-implant bone levels has gained popularity among implant manufacturers over the last few years. However, the assumption that the inward shifting of the implant- abutment junction may preserve crestal bone was primarily based on serendipitous finding rather than scientific evidence.

It is known that saucerization around an implant occurs following abutment connection using a submerged implant with a butt joint (a two-stage approach), such as the Branemark implant. The nature of saucerization varies according to implant type (one-stage or two-stage) and abutment connection type. they have reported that the factors that are the most likely causes of early crestal bone loss around implants are:

1. The micro-gap,

2. The implant crest module,

3. Occlusal overload, and

4. The biologic width around the dental implant. At the Toronto Conference 1998, the consensus with respect to bone loss around the implant was that bone loss of up to approximately 2 mm during the first year of implant function is acceptable, and at this level the implant is regarded as successful. There have been many reports on studies to ascertain the causes of bone loss around implants and clinical techniques to prevent it. Some reports published in 2005 and 2006 state that the platform switching technique, a technique in which an abutment that is one-size smaller than the implant platform is placed, prevents bone loss around the implant. However, there are only a few reports on the mechanism of action or the extent of bone loss prevention, and as such, it is difficult to say that the effect of PLS has been thoroughly examined. This review article examines the PLS technique and the bone loss preventive effect.

A lot of clinical studies discussed the concept of platform switching was extensively studied histologically and biomechanically. In histomorphometric studies in dogs was no significant difference in the marginal bone level around platform- switched and -matched implants after 28 days of healing. In contrast, other studies reported a significantly less bone loss around platform-switched implants after a loading period of 2 to 6months.

However, there is no consistency among the studies with respect to the study design (e.g. the location and depth of the implant, and controlled/non-controlled), and as such, it is difficult to evaluate all of these studies using the same evaluation method.

The review and meta-analysis show that platform switching may preserve interimplant bone height and soft tissue levels. The degree of marginal bone resorption is inversely related to the extent of the implant- abutment mismatch. But still no general agreement to confirm the validity of this concept, so Further long-term, well-conducted, randomized controlled studies are needed to confirm the validity of this concept.
