Preservación Alveolar con Técnica BARP y Provisionalización Inmediata. Caso Clínico

RESUMEN: Actualmente existen varias alternativas para prevenir, disminuir y corregir deformidades en el reborde alveolar, originadas por la reabsorción ósea al momento de la extracción de uno o varios dientes. La preservación alveolar es cualquier procedimiento que se realiza al momento de una extracción y permite conservar las dimensiones y el contorno del alveolo. Hay diversas técnicas para preservación las cuales están diseñadas para prevenir tanto como sea posible los cambios ocurridos al retirar un órgano dentario. El tratamiento de elección para reemplazar la funcionalidad, estabilidad biológica y estética de un diente, es a través de la colocación de implantes dentales, cuya colocación posterior a la preservación alveolar reduce los cambios dimensionales del reborde alveolar. La recientemente propuesta técnica de preservación alveolar BARP, "Biologically-oriented Alveolar Ridge Preservation" por sus siglas en Inglés, logró preservar las dimensiones de la cresta alveolar, al tiempo que restringe cualquier interferencia sobre el biomaterial.

ABSTRACT: Nowadays there are several choices, to prevent, reduce and correct alveolar ridge deformities caused by resorption at the time of extracting one or several teeth. Alveolar ridge preservation is defined as any procedure performed, following any dental extraction that allows the dimensions of the alveolus to be preserved. Those techniques of alveolar ridge preservation are designed to prevent as many reabsorption changes that occur after dental extraction. The best choice to replace the functionality, biological stability, and esthetic, of natural teeth is to place a dental implant. The placement of the alveolar ridge preservation treatment reduces the dimensional changes over the alveolar ridge. The recently proposed technique to alveolar ridge preservation called BARP or "Biologically-oriented Alveolar Ridge Preservation" managed to preserve the alveolar ridge dimensions while restricting any interference with the biomaterial at the same time.

A deviceful approach of managing hollow maxillary complete denture

Retention, stability and support are the most fundamental and basic principles on which the success of an entire denture relies on. However this factor is often compromised in cases of resorption. Residual ridge resorption is the reduction in size of the bony ridge under the mucoperiosteum. The rate of resorption in mandibular arch is at an increased rate as compared to the maxillary arch; but severely atrophic maxillae with large inter-ridge distance often pose a clinical challenge during fabrication of a successful maxillary complete denture because of the increased weight of the denture, retention is compromised. The present article describes a case of a completely edentulous patient who was successfully rehabilitated with a hollow denture where a simple and deviceful technique of fabricating a light-weight maxillary denture. The present article describes a case of a completely edentulous patient who was successfully rehabilitated with a hollow denture where a simple and deviceful technique of fabricating a light-weight maxillary denture was used using the hollow tubing of salivary ejector apparatus to bring the uniform hollowness.

Modified Root Submergence Technique for Pontic Site Development in Maxillary Anterior Region.

Extraction of tooth leads to alveolar ridge resorption, which is more pronounced in the 1st year after extraction. Ridge resorption results in loss of interdental papillae and creation of unesthetic black triangles. Root submergence technique (RST) is a procedure where the tooth is decoronated and submerged at or below the alveolar bone level. The goal of the technique is to maintain the attachment complex of the tooth, which will prevent the alveolar bone resorption at the site with maintained soft tissue profile resulting in better esthetic results. The present case describes a relatively bloodless and minimally invasive modified RST that can be implemented in routine clinical practice with the predictable esthetic outcome.

Oral rehabilitation through preventive approach: Overdenture and fenestrated denture.

Achieving excellence in aesthetics and preservation of remaining structure is the ultimate goal in preventive prosthodontic. Overdenture is a conservative and preventive approach and is essentially a preventive prosthodontic concept as it endeavours to preserve remaining teeth and thus found to be eminently suitable for treating patients with few remaining natural teeth . this case report discusses the merits of using selectively retained roots and abutments to minimize alveolar ridge resorption underneath the complete denture fabricated as maxillary overdenture and mandibular fenestrated denture.

Complete denture fabricated by Jiro Abe's method for edentulous patient with severe alveolar ridge resorption: a case report / 대한치과보철학회지

Fabrication of complete denture by Jiro Abe's method was introduced that enhance the retention and stability of denture by sealing around the denture border with mucous membrane to make negative pressure at the inner surface of denture base when swallowing or occlusion. In this case, taking impression and fabricating complete denture by the Jiro Abe's method for an edentulous patient with severe mandibular alveolar bone resorption allowed us to obtain clinically enhance stability of denture and improve satisfaction of patient.

Alveolar ridge preservation?: decision making for dental implant placement / Preservación del reborde alveolar?: toma de decisión ante la colocación de implantes dentales

Bone resorption is a physiological consequence of tooth loss that could be a significant functional andan esthetic risk for dental implants. The dimensional changes of the alveolar ridge could be managedwith different graft materials and surgical techniques that have been reported in the scientific literature.The purpose of this review is to explore the indications and present actual techniques to help preventresidual ridge resorption, as much as possible, guaranteeing the success of Prosthodontic rehabilitationwith implants.

La reabsorción ósea es una consecuencia fisiológica de la pérdida dental que puede convertirse en un riesgofuncional y estético significativo para la colocación de implantes dentales. Los cambios dimensionales delreborde alveolar pueden ser manejados con diferentes materiales de injerto y procedimientos quirúrgicosreportados en la literatura. El propósito de esta revisión es presentar las indicaciones y técnicas actualesutilizadas para ayudar a prevenir, en lo posible, la reabsorción del reborde residual asegurando el éxitode la rehabilitación sobre implantes.

Hollow Maxillary Denture: A Simplified Approach.

It is the dentist’s responsibility to fabricate a prosthesis incorporating stability, retention and support which ultimately provide satisfaction to the patient. But in the critical conditions such as long lip length or severely resorbed ridges with increased inter arch distance, the weight of a maxillary denture is often a dislodging factor. Hence, a light weight denture is required for better retention. This article describes a case of completely edentulous patient successfully rehabilitated with a hollow denture where a simplified technique of fabricating a light weight maxillary denture was used.

How much bone loss can be prevented by alveolar ridge preservation? Systematic literature review and meta-analysis

Aim: resorption of alveolar bone following tooth loss represents a major limitation in the use of dental implants. Procedures of ridge or socket preservation have been introduced to maintain bone dimensions and enable prosthetically driven implant positioning, yet circumventing two-stage bone graft surgery. The aim of the present systematic review and meta-analysis was to quantify reduction of alveolar ridge resorption in horizontal as well as vertical dimension (compared to untreated controls) reported in clinical trials on alveolar ridge grafting. Materials and Methods: systematic electronic and hand searches yielded 4 investigations published between 2000 and 2009 that met the inclusion criteria. A total of 74 ridge preservation procedures and 61 control sites were evaluated 6-7 months after surgery. Results: mean loss of bone height and width was 0.3 mm and 2.5 mm after ridge preservation surgery compared to 1.2 mm and 3.5 mm in the control group, respectively. Prevention of horizontal shrinkage (mean: 28%, range: 12-55%, OR = 1.6) was significantly less effective (p = 0.034) than reduction of vertical bone resorption (mean: 74%, range: 60-88%, OR = 4.9). Conclusion: alveolar ridge preservation may be effectively used to increase available bone height and width by 1 mm, on average

Prosthodontic Rehabilitation Of Mandibular Resorbed Ridge: A Different Approach.

The treatment of edentulous patient is always a challenge for the Prosthodontist. It is connected with a lot of procedures aiming to reconstruct and replace the mandible and maxilla for the patients who have lost all their remaining teeth. Treating the highly resorbed mandibular ridge accompanied with an enlarged tongue, along with the average response of the patient to all the clinical procedures, is a tedious job. The aim of this article is the prosthetic treatment of a mentally challenged patient with asymmetry of alveolar ridges, macroglossia and the difficulties related with the treatment and the suitable techniques and approaches to overcome those difficulties.
