Mechanical and fatigue resistance of restorations supported by welded-framework and realized using computer-aided designed prosthetic shells: In vitro pilot study.

Resin coating in implants rehabilitation cannot always be aesthetic, durable and comfortable for the patient mainly due to the limited dimensions of the final structure. Intraoral welding technique and computer-aided designed prosthetic shells may be a solution. This in vitro study evaluates the capacity of load and the weakest point of implant-supported provisional prosthesis using welded titanium framework.

Computer-Aided Crown Design Using Digital Scanning Technology for Immediate Postextraction Single-Implant Restorations Supported by Conical Indexed Abutments.

Conical retention with antirotational features (Acuris abutment) has been recently proposed for restorations of healed single implants. The conometric abutments use the retentive force of the coping-abutment system to retain the prosthetic crown without the use of cement or screws. This retentive force must be overcome to obtain detachment of the relined provisional crown in immediate restorations.

Guided-welded approach planning using digital scanning technology for combined screw- and conometric-retained implant-supported maxillary prosthesis.

Aim: The goal of this case series was to evaluate the clinical outcome at the 2-year follow-up of immediately loaded combined screw- and conometric-retained implant-supported full-arch restorations virtually planned using digital scanning technology.

Materials And Methods: This series included 12 patients presenting hopeless teeth in the maxilla treated with computer-guided flapless implant placement. A total of 72 implants were inserted.

Accuracy of Computer-Guided Flapless Implant Surgery in Fully Edentulous Arches and in Edentulous Arches With Fresh Extraction Sockets.

Purpose: The aim of this study was to evaluate the accuracy of computer-guided flapless implant (CGFI) surgery in edentulous jaws with fresh extraction sockets and compare it to CGFI in fully edentulous jaws.

Materials And Methods: Ten patients with a completely edentulous arch (group A) and ten patients presenting natural teeth with a hopeless prognosis in the upper or lower jaw (group B) were consecutively treated with CGFI. A multipiece radiographic guide was fabricated for group B patients.

Guided-welded approach planning using a computer-aided designed prosthetic shell for immediately loaded complete-arch rehabilitations supported by conometric abutments.

In guided surgery, implants can be planned from radiographic guide information according to a restoratively driven treatment plan. Unfortunately, the palatal or lingual surface of teeth cannot be easily identified. The present article describes the use of a digitally designed prosthetic shell to improve the accuracy of guided-welded approach planning for immediate restorations supported by conometric abutments.

Implementation of computer-guided implant planning using digital scanning technology for restorations supported by conical abutments: A dental technique.

Conometric retention has recently been proposed as an alternative to cement- or screw-retention for fixed restorations. Conometric copings can only compensate for slightly nonparallel placement without interfering with retention. This article describes a method of using digital scanning technology to facilitate computer-guided implant planning when an immediate restoration supported by conical abutments is planned with a guided-welded approach.

Use of Intraoral Welding to Increase the Predictability of Immediately Loaded Computer-Guided Implants.

Inaccuracy of computer-guided implant placement may lead to complications when combined with an immediately loaded prefabricated prosthesis. The aim of this case series was to describe the use of an intraoral welding technique to increase the predictability of immediately loaded implants supporting a fixed full-arch prosthesis after computer-guided flapless implant placement. A total of 60 Ankylos plus implants (Dentsply) with a width of 3.

A computer-guided bone block harvesting procedure: a proof-of-principle case report and technical notes.

During autogenous mandibular bone harvesting, there is a risk of damage to anatomical structures, as the surgeon has no three-dimensional control of the osteotomy planes. The aim of this proof-of-principle case report is to describe a procedure for harvesting a mandibular bone block that applies a computer-guided surgery concept. A partially dentate patient who presented with two vertical defects (one in the maxilla and one in the mandible) was selected for an autogenous mandibular bone block graft.

Computer-assisted surgery and intraoral welding technique for immediate implant-supported rehabilitation of the edentulous maxilla: case report and technical description.

Background: Complications are frequently reported when combining computer assisted flapless surgery with an immediate loaded prefabricated prosthesis. The authors have combined computer-assisted surgery with the intraoral welding technique to obtain a precise passive fit of the immediate loading prosthesis.

Methods: An edentulous maxilla was rehabilitated with four computer assisted implants welded together intraorally and immediately loaded with a provisional restoration.

Immediately Loaded Intraorally Welded Complete-Arch Maxillary Provisional Prosthesis.

Guided implant surgery is not completely accurate when using computer-designed stereolithographic surgical guides. Complications are frequently reported when combining computer-guided flapless surgery with an immediately loaded prefabricated prosthesis. Achieving passive fit of a prefabricated prosthesis on the inserted implants the same day of the surgery can be difficult.

Buccal plate regeneration with immediate postextraction implant placement and restoration: case reports.

The loss of the buccal alveolar plate following tooth extraction in the maxillary anterior region is an especially challenging condition for the clinician. Immediate implant placement with a flapless approach has been suggested in order to reduce postextraction bone loss. In the presence of a significant vertical gap in the buccal plate after tooth extraction, most authors still recommend a bone augmentation procedure before implant placement.

Endoscopically assisted enucleation and curettage of large mandibular odontogenic keratocyst.

This article reports a case of a mandibular multilocular keratocyst treated with endoscopically assisted enucleation and curettage. An ectopic third molar displaced in the coronoid process area was also removed.Odontogenic keratocysts (OKCs) are known for their propensity to recur.

Arthroscopy with open surgery for treatment of synovial chondromatosis of the temporomandibular joint.

We report a case of synovial chondromatosis of the temporomandibular joint in which both joint compartments were affected. Because of the important involvement of the medial aspect of the joint, arthrotomy was done with arthroscopic assistance.

Is there a role for arthrocentesis in recapturing the displaced disc in patients with closed lock of the temporomandibular joint?

Objective: The aim of this study was to evaluate the effectiveness of arthrocentesis in releasing acute and chronic closed lock of the temporomandibular joint, improving function, reducing pain and recapturing the displaced disc.

Study Design: We performed arthrocentesis and mandibular manipulation (MM) as an initial treatment in 33 patients (unilateral involvement) with a variable duration of closed lock and magnetic resonance imaging (MRI) evidence of anterior disc displacement without reduction (ADDWR). Duration of locking ranged from 1 week to 2 years.

Intraoral endoscopically assisted treatment of temporomandibular joint ankylosis: preliminary report.

Temporomandibular joint (TMJ) ankylosis is characterized by the formation of a bony or fibrous mass that replaces the normal articulation. To avoid a possible re-ankylosis it is mandatory to perform a radical, complete resection of the bony/fibrous mass. We treated a patient affected by right temporomandibular joint ankylosis performing the osteotomy of the ankylotic mass through a preauricular and intraoral approach under endoscopic control.

Septic arthritis of the temporomandibular joint successfully treated with arthroscopic lysis and lavage: case report and review of the literature.

Septic arthritis of the temporomandibular joint (TMJ) is infrequently reported. We present a case of septic arthritis of the TMJ following the extraction of the left upper second molar that occurred 1 week before beginning of symptoms. No evident predisposing factors were detected.
