AIM To assess in a randomized study the patient-centred outcome of two guided surgery systems (mucosa or bone supported) compared to conventional implant placement, in fully edentulous patients. MATERIAL AND METHODS Fifty-nine patients (72 jaws) with edentulous maxillas and/ or mandibles, were consecutively recruited and randomly assigned to one of the(More)
AIM To give an overview of the workflow from examination to planning and execution, including possible errors and pitfalls, in order to justify the indications for guided surgery. MATERIAL AND METHODS An electronic literature search of the PubMed database was performed with the intention of collecting relevant information on computer-supported implant(More)
The purpose of the present paper is to review the literature on the use of CT scan based planning for oral rehabilitation and its transfer to the surgical field by means of a surgical guide. The first part will deal with surgical guides based on tomographies or CT scan data often using dedicated software, but manually fabricated. In the second part,(More)
OBJECTIVE This retrospective analysis evaluated the long-term outcome of two implants supporting an overdenture in the mandible, as well as the significance of some confounding factors (smoking, implant length, bone quality). MATERIAL AND METHODS All mandibular overdenture cases (n=495) treated during the past 25 years in our centre (with > or = 5 years(More)
Different computer-assisted implant-placement procedures are currently available. These differ in software, template manufacture, guiding device, stabilization and fixation. The literature seems to indicate that one has to accept a certain inaccuracy of ±2.0 mm, which seems large initially but is clearly smaller than for nonguided surgery. A reduction of(More)
For computer-guided surgery a static surgical guide is used that transfers the virtual implant position from computerized tomographic data to the surgical site. These guides are produced by computer-aided design/computer-assisted manufacture technology, such as stereolithography, or manually in a dental laboratory (using mechanical positioning devices or(More)
AIMS The aims of this review are twofold, firstly, to give an overview of the general and local risk factors when using temporary anchorage devices (TADs) and the prerequisites for placement and, secondly, to illustrate the orthodontic indications of various TADs. METHODS The PubMed database was searched for original articles on: 'orthodontics and(More)
OBJECTIVE Several theories have been presented to explain initial and secondary marginal bone loss around dental implants (e.g. microbial load, adverse loading, microbial leakage, compromised healing/adaptation of host-implant interface). MATERIAL AND METHODS This study compared the long-term outcome (up to 12 years) of sleeping with loaded implants in(More)
AIM To assess the accuracy of static computer-guided implant placement. MATERIAL AND METHODS Electronic and manual literature searches were conducted to collect information on the accuracy of static computer-guided implant placement and meta-regression analyses were performed to summarize and analyse the overall accuracy. The latter included a search for(More)
OBJECTIVE In part 2 of this long-term, retrospective study on the two-implant-supported overdenture in the mandible, the annual marginal bone loss was evaluated in detail and parameters, with a significant effect on the annual bone loss, were verified. MATERIAL AND METHODS For all 495 patients with an overdenture in the mandible at least 5 years in(More)
