Biologic and Technical Complications of Implant-Supported Immediately Loaded Fixed Full-Arch Prostheses: An Evaluation of Up to 6 Years.

Purpose: Treatment by means of implant-supported immediately loaded fixed full-arch prostheses is known to be related to biologic and technical complications. The aim of this retrospective study was to investigate the prevalence and moment of occurrence of biologic and technical complications happening in immediately loaded fixed full-arch prostheses.

Materials And Methods: This study investigated patients who received treatment with immediately loaded fixed full-arch prostheses using four to six implants from 2007 to 2013.

"Teflon tape technique": synergy between isolation and lucidity.

The aim of this article is to introduce and illustrate the "Teflon tape technique," which provides good lucidity in combination with excellent isolation of the working field. It is intended to serve as a supplement to the gold standard rubber dam for the adhesive working dental practitioner. Primarily, the Teflon tape technique (Teflon is a registered trademark, and not affiliated with Teflon tape) is particularly suitable for the adhesive cementation of restorations with very thin margins.

Implant-Supported Immediately Loaded Fixed Full-Arch Dentures: Evaluation of Implant Survival Rates in a Case Cohort of up to 7 Years.

Background: The treatment of severely atrophied and edentulous jaws by means of fixed implant supported solutions is a challenging procedure.

Purpose: The immediate loading of four to six axial and tilted implants offers the possibility to overcome elaborate hard tissue augmentation procedures but lacks implant and patient related data on implant survival rates.

Materials And Methods: This retrospective 7-years clinical trial investigated the implant survival rates of 2,081 implants (380 patients, 482 jaws) using an immediate loading protocol with either 4, 5, or 6 implants per restoration.

Zygomatic implant placement in conjunction with sinus bone grafting: the "extended sinus elevation technique." a case-cohort study.

Purpose: The zygomatic implant is mainly indicated for the rehabilitation of extremely atrophied maxillae when bone augmentation should be avoided. One drawback of zygomatic implants, which typically pass through the sinus, is initial or late bone resorption around the implant neck, which can result in oroantral communications followed by possible infection of the sinus. To decrease the risk of sinus infection, a modified technique was developed to preserve the integrity of the sinus membrane and to regenerate bone around zygomatic implants using an extended sinus grafting approach.

The bone lamina technique: a novel approach for lateral ridge augmentation--a case series.

The goal of this case series is to present a novel treatment approach for lateral ridge augmentation. Four systemically healthy patients (aged 48 to 59 years) with inadequate dental alveolar ridge widths were selected for inclusion. All ridge defects were augmented using a xenogeneic cortical bone shield in combination with particulated bone substitutes and a thin collagen barrier.

The Healing of Free Gingival Autografts for Socket-seal Surgery: a Case Report.

Tooth extraction will be followed by marked alterations to the tissue volume, in particular in the anterior zone, which may jeopardize the esthetic outcome of any dental treatment involving tooth extraction. If, however, ridge collapse can eb prevented or minimized after tooth extraction, more predictable outcomes with superior esthetics can be accomplished along with fewer surgical procedures. Therefore, it was proposed that stabilizing the soft tissue architecture with a free gingival graft could minimize the soft tissue shrinkage.

Immediate loading of fixed provisional prostheses using four implants for the rehabilitation of the edentulous arch: a prospective clinical study.

Purpose: The purpose of this prospective clinical trial was to evaluate over a 5-year period the treatment outcomes for immediately loaded full-arch fixed prostheses supported by two axially inclined and two tilted implants used to rehabilitate edentulous arches. This report presents preliminary 1-year results.

Materials And Methods: Thirty-seven patients were recruited for treatment with either mandibular or maxillary full-arch fixed prostheses supported by four implants.

The friction free osteotome technique: introduction of a modified approach.

The current literature suggests that the bone-condensing approach while performing internal sinus floor elevation may not be beneficial for the future implant site. Furthermore, even with refined procedures, a predictable and controlled infraction of the sinus floor prior to graft placement still seems to be technique sensitive. In this context, the present article presents a modified technique along with the use of parallel osteotomes devoid of any contact to the lateral osteotomy wall.

The double split flap: a surgical approach for regenerative treatment of interproximal defects.

Aims And Background: Primary wound closure has been advocated to be indispensable for a successful outcome of guided tissue regeneration-procedures. Yet narrow inter-proximal spaces often lack sufficient tissue quantity in order to facilitate a tension free re-adaptation of periodontal flaps. In order to maintain an uneventful healing process, the concept of layer-wise wound closure is applied to periodontal surgery.

Hard tissue alterations after socket preservation: an experimental study in the beagle dog.

Objectives: The aim of the following experimental study was to assess bone changes in the horizontal and vertical dimension when using different socket preservation procedures.

Material And Methods: In five beagle dogs the distal roots of the 3rd and 4th premolar were extracted without elevation of a mucoperiosteal flap and the following treatments were assigned: Tx 1: The extraction socket was filled with BioOss Collagen (Geistlich Biomaterials, Wolhusen, Switzerland) and interrupted sutures were applied.: Tx 2: The extraction socket was filled with BioOss Collagen (Geistlich Biomaterials, Wolhusen, Switzerland) and a free gingival graft was sutured to cover the socket.

Tissue alterations after tooth extraction with and without surgical trauma: a volumetric study in the beagle dog.

Objectives: The aim of this study is to evaluate whether tooth extraction without the elevation of a muco-periosteal flap has advantageous effects on the resorption rate after tooth extraction.

Material And Methods: In five beagle dogs polyether impressions were taken before the surgery. The roots of the first and second pre-molars (P(1) and P(2)) were extracted and the sites were assigned to one of the following treatments: treatment group (Tx) 1, no treatment; Tx 2, surgical trauma (flap elevation and repositioning); Tx 3, the extraction socket was filled with BioOss Collagen and closed with a free soft-tissue graft; Tx 4, after flap elevation and repositioning, the extraction socket was treated with BioOss Collagen and a free soft-tissue graft.

Covering of gingival recessions with a modified microsurgical tunnel technique: case report.

Recent advances in periodontal plastic surgery have encouraged reassessment of the envelope technique and its modified version, the tunnel technique, for root coverage. This article describes alterations in the technique-sensitive tunnel approach, which include an undermining split flap preparation of the buccal tissues with newly developed instruments to minimize trauma and ensure a better blood supply for the connective tissue graft. The use of a microsurgical concept, including microsurgical blades and suture material, improves wound healing and establishes a better esthetic result.

Distraction osteogenesis: a treatment tool to improve baseline conditions for esthetic restorations on immediately placed dental implants--a case report.

Replacement of two adjacent teeth in an anterior maxilla with deficient hard and soft tissues appears to be the utmost challenge in implant dentistry in the esthetic zone. In this case report, baseline conditions for implant placement were improved by alveolar distraction to enhance hard and soft tissues around the maxillary central incisors. Three months after the active phase of distraction, the roots of the central incisors were extracted and two screw-type dental implants were immediately placed into the extraction sockets.
