PURPOSE The aim of the study was to examine the influence of a short drilling protocol on peri-implant crestal bone levels. MATERIALS AND METHODS Forty implants were placed in the posterior mandibles of 20 patients. The implants (diameter, 4.2 mm; length, 10 to 11.5 mm) were inserted in pairs: one implant was inserted using the standard drilling protocol (five drills in sequence), while the o...

OBJECTIVE Several appliances have been used for palatal expansion for treatment of posterior cross bite. The purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (FEM) analysis. MATERIALS AND METHO...

BACKGROUND The aim of the study was to evaluate whether early loading of implants with a chemically modified sandblasted, large-grit, acid-etched (SLA) (SLActive®) surface was non-inferior to conventional loading in terms of change in crestal bone level. METHODS This was a randomized, controlled, multicenter study. Patients requiring single-tooth rehabilitation in the posterior maxilla or man...

The aim of this study was to determine the relationship between loss of radiographic crestal bone height in panoramic, bitewing and periapical radiography and to probe the attachment loss after periodontal treatment. Radiographic and probing measurements were made at baseline and after one year The population in the study consisted of 21 individuals, 13 females and 8 males, ages 18-59 [mean 35....

STATEMENT OF PROBLEM Zirconia implants have been used for oral rehabilitation; however, evidence of their ability to maintain crestal bone and periimplant soft tissue health is not clear. PURPOSE The purpose of this systematic review was to evaluate crestal bone loss (CBL) around zirconia dental implants and clinical periimplant inflammatory parameters. MATERIAL AND METHODS The focus questi...

STATEMENT OF PROBLEM Load transfer mechanisms and possible failure of osseointegrated implants are affected by implant shape, geometrical and mechanical properties of the site of placement, as well as crestal bone resorption. Suitable estimation of such effects allows for correct design of implant features. PURPOSE The purpose of this study was to analyze the influence of implant diameter and...

background: the aim of this study is to evaluate and compare the crestal bone loss and stability of single mandibular posterior dental implants placed in immediate functional loading (ifl) and immediate nonfunctional loading (infl) during 6 months after placement. materials and methods: forty single piece root form titanium implants were placed in 20 patients using ifl and infl techniques. the ...

BACKGROUND Today, implants are placed using both non-submerged and submerged approaches, and in 1- and 2-piece configurations. Previous work has demonstrated that peri-implant crestal bone reactions differ radiographically under such conditions and are dependent on a rough/smooth implant border in 1-piece implants and on the location of the interface (microgap) between the implant and abutment/...
