The conventional placement protocol for submerged and non-submerged implants was proposed in the 1960s and 1970s. Multicenter studies have reported satisfactory success rates for both protocols and a similar loss of crestal peri-implant bone after implant loading (0.5 to 1.5 mm). In recent years, placement of submerged implants using a single surgical procedure was introduced, with the immediat...

The objective of this study was to compare the alveolar bone growth in the 2 sides of the maxillary sinus after bilateral sinus lift procedures were performed with the simultaneous placement of dental implants in 20 consecutive patients. After elevation of the Schneiderian membrane, one side had only platelet-rich plasma (PRP) gel applied, while the other had placed only alloplastic graft mater...

OBJECTIVES The aim of this consensus meeting was to assess the impact of implant-abutment connection, positioning of the machined collar/microgap, and platform switching on crestal bone level changes. MATERIALS AND METHODS Two comprehensive systematic reviews were prepared in advance of the meeting. Consensus statements, practical recommendations, and implications for future research were bas...

Dental materials especially orthodontic elastics often get embedded in gingival tissues due to iatrogenic factors. If retained for a long time, inflammatory response starts as asymptomatic crestal bone loss and may progress to severe periodontal abscess. Unsupported orthodontic elastics used for diastema closure may result in exfoliation of teeth, while elastic separators may get embedded in in...

In 61 patients, 61 consecutive implants were placed immediately after extraction of one anterior or premolar maxillary tooth. One of 3 surgical approaches based on rotated full (RPF) or rotated split (RSPF) palatal flaps, with and without the use of barrier membranes to enable primary soft tissue closure, was applied. A bovine bone mineral graft was used in all cases. At the time of implant pla...

There is no consistent relationship between malocclusion and periodontal disease but certain characteristics of malocclusion can promote a pathologic environment conducive to periodontal disease. One of the dramatic means available to improve the local environmental factors is through orthodontic tooth movement. The pretreatment periodontal conditions can include excessive tooth mobility, advan...

The anterior maxilla represents a therapeutic challenge for single-tooth replacement with implants. The surgical trauma delivered to soft and hard tissues during implant placement can influence the future esthetic result. The clinician should use surgical techniques that prevent esthetic complications, such as increased crown length or loss of interdental papillae, without compromising osseoint...

Platform switching is the use of smaller diameter abutments on wider diameter implants. It is used as a method of reducing crestal bone loss and maintaining the gingival papillae. Platform switching appears to limit crestal resorption and seems to preserve peri-implant bone levels. A certain amount of bone remodeling one year after final restoration occurs, but significant differences concernin...
