Extrusive luxation. Therapeutic procedure.

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. Abstract: Repositioning a traumatized tooth involves, first, replacing and second stabilizing it. Stabilization, on the other hand, usually requires flexible splints. Occasionally the immediate replacement may be impossible being necessary to use other procedure. When complete replacement is not possible.

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. We present a study protocol that analyzes three basic prosthetic aspects. First, denture space defines the need to replace teeth, tissue, or both. Second, lip support focuses on whether or not to include a flange. Third, the smile line warns of potential risks in esthetic rehabilitation. Combining these parameters allows us to make a decision as to the most suitable type of prosthesis. The proposed protocol is useful for assessing the prosthetic parameters that influence decision making as to the best-suited type of restoration. From this point of view, we think it is appropriate for the initial approach to the patient. In any case, other considerations of study may amend the proposal.

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. The authors present a case in which the palatal defect has increased overtime. After placement of a sealing prosthesis with implants, bone and mucosal tissues stability around the defect it is observed during 1 year of follow-up.

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. The obturator comprised a metal framework for dental retention and to prevent displacement and a resin obturator to block the defect. In addition, acrylic resin facilitated adjustments due to the fact that it is easy to adapt to changes in the size of the palatal defect.

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. The palatal plate was adapted to conform in a passive manner to the soft palate with light-cured resin. The designed PLP simplified the procedure and reduced the number of adjustments and visits.

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. The inclination has been solved by making a bar on the right side and individual pillars on the left side so as to obtain a functional and esthetic prosthetic result.

A paralleling technique modification to determine the bone crest level around dental implants.

The aim of this report is two-fold. First it analyses the precision of a modification of the parallel technique that can be used in those cases with anatomical limitations. Second, it checks the influence of the reference points' definition of objects to be measured by using both the original and the modified radiographic techniques. 2 intraoral radiographs were taken of 28 implants with 2 different methods: a standard paralleling technique and a modified technique that used a smaller film and a silicone spacer to ensure parallelism. Measurements of peri-implant bone levels and implant width were made in triplicate on digitized film radiographs. The results of the peri-implant bone levels were that with the parallel method the mean was 0.44 mm and the precision was 0.43 mm, and with the modified method the mean was 0.73 mm and the precision was 0.66 mm. In addition to the correct localization of the point of reference in this study, the precision with the parallel method was 0.08 mm and with the modified method was 0.13 mm. Although it was greater with the gold standard technique than with the modified technique, precision was very high for both methods and accurate enough for clinical use.
