The present study investigated 124 stepped-screw implants (gritblasted and acid-etched surface) placed in 104 patients immediately after tooth extraction or implant explantation and followed between August 1990 and December 1996. Implants of varying diameters and lengths were used to cover a wide range of indications in both the maxilla and mandible; 68% of the implants supported single-tooth r...

BACKGROUND Primary stability (PS) is a key factor for implant survival rate and depends on implant design or bone quality. The aim of this study was to compare different thread designs implants, evaluating PS with periotest values (PV) and implant stability quotient (ISQ) values through resonance frequency analysis (RFA). MATERIAL AND METHODS A total of 60 implants (Radhex®, Inmet-Garnick S.A...

The main criterion for assessing the engraftment of dental implants is their high-quality osseointegration [1]. Unreasonable loads exerted on a implant integrated into bone tissue lead to its premature rejection. Adequate also influenced by shape, size, quality installation, adherence operating protocol, as well start date subsequent prosthetics [2]. A qualitative method determining stability a...

Purpose: To evaluate wide-diameter (ie, 5.5-mm-wide) Frialit-2 implants used for several forms of prosthetic rehabilitation. Materials and Methods: In this retrospective study, 121 wide implants (74 maxillary, 47 mandibular) were placed in 114 patients (61 female, 53 male, mean age 37.2 ± 14.9 years). Thirty-six single-tooth restorations, 63 fixed partial dentures (68 implants), 6 removable ove...

The aim of the study was to evaluate tooth mobility in relation to root length and alveolar bone support in maxillary incisors 10-25 years after orthodontic treatment, and to monitor the development during 5 years in a sub-sample. Thirty-six patients, seven males and 29 females with one or more severely resorbed maxillary incisors, a total of 139 teeth, were examined. At re-examination, 11 pati...

BACKGROUND The zygoma implant has been an effective option in the short-term management of the atrophic edentulous maxilla. PURPOSE To report on long-term outcomes in the rehabilitation of the atrophic maxilla using zygomatic (ZI) and regular implants (RI). MATERIAL AND METHODS 22 consecutive zygomatic patients in a maintenance program were included. Cumulative survival rate (CSR) of ZI, RI...

OBJECTIVE To compare the clinical soft tissue responses around implant tooth-supported 3-unit bridges using tapered abutments with those using butt-joint abutments. METHODS In a split-mouth design study, 8 mm Ankylos (Dentsply Friadent, Germany) implants were placed in the second mandibular molar region of 8 adult Macaca fascicularis monkeys about 1 month after extraction of all mandibular mo...

This study was designed to compare the results of immediate and delayed loading of implants with implant-retained mandibular overdentures. Ten patients (test group) received 40 Brånemark System MKII implants (4 per patient) placed in the interforaminal area of the mandible. Standard abutments were immediately screwed to the implants, rigidly connected with a bar, and immediately loaded with an ...
