Extrusive luxation. Therapeutic procedure.

Unlabelled: Repositioning a traumatized tooth involves replacing and stabilizing it. When it is not possible, a method has been developed by an acetate splint. After few weeks, the tooth was aligned and correctly positioned.

Radiographic Assessment Of Crestal Bone Loss In Tissue-Level Implants Restored By Platform Matching Compared With Bone-Level Implants Restored By Platform Switching: A Randomized, Controlled, Split-Mouth Trial With 3-Year Follow-Up.

Purpose: This randomized, controlled, split-mouth trial with 3-year follow-up was carried out to compare radiologic changes of crestal bone level (CBL) between splinted tissue-level implants restored by platform matching and bone-level implants restored by platform switching.

Materials And Methods: Periapical radiographs were taken to evaluate the peri-implant crestal bone changes at baseline (implant restoration), at 1 year, and at 3 years after the definitive restoration.

Results: Thirty-five patients requiring a partial fixed dental prosthesis supported by two implants had their sites randomized according to receiving both implant types.

Crestal Bone Level Around Tissue-Level Implants Restored with Platform Matching and Bone-Level Implants Restored with Platform Switching: A 5-Year Randomized Controlled Trial.

Purpose: The aim of this randomized clinical trial with a 5-year follow-up was to assess the differences in radiographic levels of peri-implant bone crest between tissue-level implants restored with platform matching (control group) and bone-level implants restored with platform switching (test group) in the posterior region.

Materials And Methods: To assess marginal bone level changes, periapical radiographs were taken at the moment of prosthesis delivery (baseline), at 1 year, and at 5 years after the definitive restoration.

Results: One hundred subjects, partially edentulous in the posterior region, were selected for this study.

Bone and Soft Tissue Response in Bone-Level Implants Restored with Platform Switching: A 5-Year Clinical Prospective Study.

Purpose: The aim of this prospective study was to evaluate radiographic levels of peri-implant bone crest as well as soft tissue response, papilla height, and buccal mucosa recession, in bone-level implants restored with platform switching after 1-year and 5-year follow-ups.

Materials And Methods: This prospective study called for the placement of 59 implants to obtain a target of 90% power. To compensate for possible dropouts, the sample size was adjusted to 67 implants.

A New Approach to the Use of Osseointegrated Implants in Palate Obturator.

Osseointegrated implants are regularly used for retention and stability of maxillofacial prosthesis, especially in palatal obturator with large defects and few remaining teeth. In these cases, loads that tissues receive from a prosthesis can cause bone resorption and thus enlarge the defect. Implants may help redistribute the loads on the perimplant bone crest and avoid exacerbating the defect.

Implant Rehabilitation Planning Protocol for the Edentulous Patient According to Denture Space, Lip Support, and Smile Line.

Rehabilitation with implants is a challenge. Having previous evaluation criteria is key to establishing the best treatment for the patient. In addition to clinical and radiological aspects, the prosthetic parameters must be taken into account in the initial workup, since they allow discrimination between fixed and removable rehabilitation.

Prosthetic Management for a Palatal Perforation from Cocaine Abuse.

The intranasal inhalation of cocaine predisposes the user to a wider range of local and systemic complications. This article describes the history of a 31-year-old woman with a palatal perforation produced by the chronic use of cocaine. In view of the doubts about abstinence from cocaine abuse, prosthetic management was chosen.

A simplified palatal lift prosthesis for neurogenic velopharyngeal incompetence.

Velopharyngeal incompetence is a contributing factor to speech disorders and implies the presence of hypernasality, inappropriate nasal escape, and decreased air pressure during speech. One prosthetic treatment is a rehabilitative procedure employing a palatal lift prosthesis (PLP), which reduces hypernasality by approximating the incompetent soft palate to the posterior pharyngeal wall and consists of two parts, the anterior denture base and the palatal lifting plate, which are connected with steel wires; however, it seems difficult to reproduce the mobility of the soft palate in speaking, and it is therefore likely that the palatal lifting plate stimulates or oppresses the tissue of the soft palate and hinders rather than assists articulatory function. To avoid these disturbances we devised an adjustable PLP with a flexible conjunction between the denture base and the palatal lifting plate to obtain the optimal vertical lifting angle.

A prosthetic alternative for severely angled implants beneath a maxillary overdenture: a clinical report.

Implant-retained overdentures have been shown to be a predictable, accepted option and represent a viable and cost-effective treatment; however, patients with severe lack of bone volume and anatomical limitations are often a contraindication to the placement of osseointegrated implants without prior surgical procedures. In these situations, the placement of angled implants may offer a simple solution. This clinical report describes a case of dental rehabilitation using angled implants for a patient with a severely resorbed edentulous maxilla.

Guidelines for occlusion strategy in implant-borne prostheses. A review.

Medium- or long-term failure of endosseous dental implants after osseointegration, when it has occurred, has been associated in the great majority of cases with occlusal overload. Overload depends ultimately on the number and location of occlusal contacts, which to a great extent are under the clinician's control. Much of our current understanding of occlusal contacts in this context is based on concepts derived from non-implant-borne prosthetics and has not been rigorously tested.

Midline shift and lateral guidance angle in adults with unilateral posterior crossbite.

Introduction: Unilateral posterior crossbite is a malocclusion that, if not corrected during infancy, typically causes permanent asymmetry. Our aims in this study were to evaluate various occlusal parameters in a group of adults with uncorrected unilateral posterior crossbite and to compare findings with those obtained in a group of normal subjects.

Methods: Midline shift at maximum intercuspation, midline shift at maximum aperture, and lateral guidance angle in the frontal plane were assessed in 25 adults (ages, 17-26 years; mean, 19.

Unilateral posterior crossbite and mastication.

Objective: This study was designed to characterize masticatory-cycle morphology, and distance of the contact glide in the closing masticatory stroke, in adult subjects with uncorrected unilateral posterior crossbite (UPXB), comparing the results obtained with those obtained in a parallel group of normal subjects.

Study Design: Mandibular movements (masticatory movements and laterality movements with dental contact) were registered using a gnathograph (MK-6I Diagnostic System) during unilateral chewing of a piece of gum. Traces were recorded on the crossbite and non-crossbite sides in the crossbite group, and likewise on both sides in the non-crossbite group.

A titanium and visible light-polymerized resin obturator.

Obturator prostheses are typically large, and their weight and size are often important design factors. This article describes the fabrication of an obturator prosthesis with a titanium framework and visible light-polymerized denture base resin. It is speculated that these low-density materials may produce prostheses lighter than similar ones made with conventional materials.
