Several important issues concerning occlusal reconstruction / 华西口腔医学杂志

Occlusal reconstruction aims to restore the compromised dentition and rehabilitate its function; which is demanding and challenging, even to the well experienced prosthodontists. Analyzing the sophisticate clinical information gives fundamental validity to the subsequent treatment planning. In the whole process, the applied workflow should ensure the transmission of diagnostic information without compromise or error. Certain procedures predetermine the clinical outcome, and they should be given due attention. In this review, the key considerations, including analyzing the pathogenesis for the worn dentition, were briefly addressed to better understand the occlusal reconstruction.

Occlusal Splint: A Vital Adjunct in Full Mouth Rehabilitation for Cases of Severely Worn Dentition

Introduction: Excessive wear of dentition results infunctional disharmony, loss of esthetics, pulpal injuries andcompromises longevity of dentition adversely. The etiologicalfactors of tooth wear may be abrasion, attrition, or erosionacting individually or in combination.Case Report: The present case report emphasizes the use ofa ‘sectional occlusal verticalization splint’, as a guide for fullmouth rehabilitation. As the treatment plan envisaged wasocclusal rehabilitation using reorganized approach, sectionalsplint offered the advantage of restoring the exact amount ofvertical dimension to which patient had got programmed. Thevertical dimension was maintained during various phases ofsegmental technique using sectional splint.Conclusion: Although there are plethora of philosophiesand techniques available for full mouth rehabilitation thereis a limited evidence-based literature on a particular methodfor exact restoration of vertical dimension. Also, due topresence of many hard and soft tissues variables in humanstomatognathic system, making various occlusal records andrepeated transfer to mechanical articulator may introduceerrors. Therefore, an occlusal ‘verticalization splint’, wellaccepted by patients stomathognathic dynamics, may act asthe best guide to restore vertical dimension with an addedadvantage of reduction in errors due to omission of varioussteps of occlusal recordings, transfers and use of mechanicaldevices.

Complete mouth rehabilitation with vertical dimension increase in patient with extremely worn dentition / 대한치과보철학회지

Generalized severely worn dentition causes occlusal disharmony, esthetic problems, and temporomandibular joint disorders. In order to solve these problems, it is necessary to make a precise analysis of vertical dimension and treatment plans considering it. This case report demonstrates the complete mouth rehabilitation of a 58-year-old male patient with a lot of worn teeth by increasing vertical dimension. Provisional restorations were cemented and after 4 months of evaluation for patient's compliance, permanent prostheses were fabricated. With these treatments, functionally and esthetically satisfactory results were obtained.

Full-mouth rehabilitation with vertical dimension increase and computer tomography guided implant surgery in patient with excessive worn dentition and multiple loss of tooth / 대한치과보철학회지

Excessive wear causes many complications when untreated, so that accurate diagnosis, analysis and predictive treatment plan should be made, and through evaluation of vertical dimension and stepwise treatment, a stable inter-arch relationship can be set. For the long-term success of implant treatment, ideal position and angle of implant is important, and its importance increases especially in multiple implant cases. Therefore, thorough diagnosis and planning, accurate surgery and prosthodontic procedures are significant. In this case, a 68-year-old male patient with a loss of vertical dimension due to multiple tooth loss and overall tooth wear was planned with systematic analyses from the pre-treatment stage to rehabilitate vertical dimension. Full-mouth fixed rehabilitation with computer tomography guided implant surgery was performed to the newly set vertical dimension and attained satisfactory outcomes both functionally and esthetically.

Full mouth rehabilitation in a patient with reduced vertical dimension due to numerous tooth loss and excessie worn dentition: A case report / 대한치과보철학회지

As digital dentistry technology is being developed, it is being used in various ways. This case covers how digital dentistry technology is being applied on the treatment of patients with loss of vertical dimension due to worn dentition and multiple loss of teeth. The loss of vertical dimension was carefully assessed and recovered, and implants were placed with surgical guides, designed considering the final restoration. The movement of the mandibular was measured with the electronic instrument for recording mandibular movement. Wax-up process was done with Naturgemäße Aufwachs-Technik (N.A.T.) and Natural functional reconstruction (N.F.R.). It was scanned, and the provisional restoration was fabricated using Computer-Aided-Design/Computer-Aided-Manufacturing (CAD/CAM) technology, and the adjustment process was done at the clinic to meet with the satisfaction both functionally and esthetically, and then, using double scanning and CAD/CAM technology, it was carried out as a final restoration. As a result, the patient obtained satisfying results, utilizing the benefits of digital dentistry technology and traditional methods.

Full mouth rehabilitation in patient with loss of vertical dimension and deep bite due to worn dentition / 대한치과보철학회지

Gradual occlusal attrition is a normal process of aging. However, severe attrition causes pathogenic pulp, occlusal disharmony, functional disorder and esthetic problems. Alteration of vertical dimension should be considered for space regaining for tooth restoration, esthetic improvement or correction of occlusal relationship. Vertical dimension should be determined within the range of minimal invasive process satisfying patient's esthetic requirements and operator's functional goal. And patient's adaptation to newly determined vertical dimension should be assessed simultaneously. Deep overbite is not a simple problem of overbite, instead it is an usually complicated problem with anterior-posterior occlusal relationship. Considering these facts, appropriate restoration of edentulous part as well as improvement of anterior-posterior relationship should be performed to solve this fundamental problems. In this study, a 67 year-old male patient with many worn teeth and loss of posterior teeth was treated with removable partial denture at edentulous mandibular area to increase vertical dimension and fixed prostheses at dentulous maxillary and mandibular area. With these treatments, we attained a satisfactory result in functional and esthetic aspects as a report case.

Full mouth rehabilitation using zirconia crown in severe worn dentition: a case report

The progressive attrition of teeth is a normal process by aging. However, excessive tooth wear with decreased vertical dimension of occlusion and collapse of occlusal plane may cause pathologic pulpal condition, occlusal disharmony and functional disorders. In this case, a patient with severely worn dentition was treated. Diagnostic wax-up was performed at the increased vertical dimension. After evaluation of provisional restorations for 12 weeks, final restorations were fabricated with zirconia crown and routine clinical assessments were made. Esthetically and functionally satisfactory results were obtained.

Overdenture treatment in patient with severely worn dentition: a case report

Overdenture is one of the methods of patients with severely worn dentition. Remaining natural teeth help preserve alveolar bone and proprioception and provide rigid support. Also, overdenture distributes the concentrated stress applied to the abutment tooth and denture supporting tissues. There is an advantage that it can provide long-term stability to denture. In this case, the patient with only a few teeth due to severe wear and caries was satisfied with good function and favorable esthetics by using overdenture.

Functional And Esthetic Rehabilitation Of Severely Worn Dentition With Shortened Dental Arch Concept.

In the twenty-first century, patterns of dental disease in adults are changing. Surveys of adult dental health indicate that more people are keeping their teeth for longer in life. In many cases, the ravages of dental disease and the cumulative effect of a lifetime of restorative dentistry lead to gradual tooth loss. For many of these patients, restoration of a complete dentition may neither be feasible nor desirable. In recent years, functionally oriented treatment planning has become acceptable in light of recent research findings. Using this approach, treatment efforts and resources are directed principally at retaining the 'strategic' part of the dentition in the long term, ie, the anterior and premolar teeth.
