A tooth that has been properly treated endodontically should have a good prognosis. It can resume full function and if necessary serve satisfactory as an abutment for a fixed and removable partial denture. However special techniques are needed to restore such a tooth. Traditionally, a pulpless tooth received a dowel or post to “reinforce” it and a crown to “protect” it. Until the introduction of ZnPO4 cement in the last century. The major problem with their use was that of post retention. Currently, the clinician can use a variety of port and core systems for the different endodontic and restorative requirements. However, no single system provides the perfect restorative solution for every clinical circumstance, and each situation requires individual evaluation.

Removable Prosthesis

The main aim of prosthetic dentistry is restoring the form, function, comfort and appearance of the patient by the placement of a prosthesis replacing the missing teeth and contiguous tissues.1 Various prosthetic options for partially edentulous patients include an interim removable partial denture (RPD) to a cast partial denture, a fixed dental prosthesis (FDP), and a more implant-retained prosthesis. However, FDP and implant-retained prosthesis are not always feasible, particularly in patients with excessive residual ridge resorption and jaw defects due to trauma and / or surgical ablation. In such a situation, a dentist may resort to another option of fixed-RPD prosthesis, to restore the defective hard and soft tissues to achieve natural aesthetics, phonetics, comfort, and better hygiene. This hybrid prosthesis fulfils the objectives of the rehabilitation such as support, stability, and retention characteristics similar to a fixed prosthesis and aesthetics and hygiene maintenance of a removable prosthesis.2,3,4,5 Any prosthesis designed or fabricated should be based on the prosthetic principles of support, stability, retention, and preservation of remaining structures.1 From the patient's perspective, retention is one of the important factors for its acceptability. These retentive options range from simple bar and clip attachments to more sophisticated spark erosion overdentures.6,7 Spark erosion prosthesis is technique sensitive, bulky, and requires expensive equipment.6,7 On the other hand, precision attachments provide better vertical support and stimulation to the underlying tissue through intermittent vertical massage.8 Treatment with a hybrid denture is an affordable choice to fulfil the patient's aesthetic demands along with providing a good prognosis for the prosthesis and preservation of the remaining dentition. This article presents two case reports of prosthodontic rehabilitation of a patient with mandibular defects using an attachment-retained fixed-removable hybrid prosthesis.

(1) Background: The degree of satisfaction with dental treatment varies among patients, and the discrepancy may exist between the patient’s subjective evaluation and the objective assessment. Further, the optimal methods for increasing patient satisfaction with mastication remain unclear. This study aimed to identify factors affecting masticatory satisfaction in patients with removable partial dentures. (2) Methods: A total of 132 participants (71.0 ± 9.0 years) were included. Masticatory satisfaction was assessed on a visual analog scale. An oral health survey was conducted to assess the number of functional teeth, missing tooth classification: Kennedy classification, occlusal support: Eichner classification, and removable partial dentures wearing jaw. Objective masticatory performance was assessed using gummy jelly, while subjective masticatory ability was assessed using food acceptance status and oral health-related quality of life. The associations of these factors with masticatory satisfaction were assessed. (3) Results: Masticatory satisfaction among removable partial denture wearers was not significantly associated with gender, age, denture wearing jaw, Kennedy classification, and occlusal support. The degree of masticatory satisfaction was significantly greater with higher levels of masticatory function: masticatory performance, food acceptance score, and OHIP-14 score. The OHIP-14 score was the only significant explanatory variable for masticatory satisfaction in the multiple regression analysis; the strongest associations were with the “psychological discomfort” and “physical disability” subscales (p = 0.02 and p = 0.005, respectively). (4) Conclusions: Masticatory satisfaction among removable partial denture wearers was strongly associated with oral health-related quality of life, in which the ability to eat meals comfortably with removable partial dentures is the most important determinant of masticatory satisfaction.

First Case

The paper presents the study of the stresses and the displacements that appear in different areas of the removable partial denture (RPD) with extracoronal attachments under occlusal loading, using FEA. The first step was to create the 3D model of a RPD with ball attachments in case of a class I Kennedy edentulous patient with all six anterior teeth as abutments. All materials were considered homogeneous, isotropic and having linear elasticity. There were assumed two types of constraints: in the first one the model is fixed under the action of the mastication forces; in the second one the rotational movement of the denture’s saddles in the sagittal plane was simulated, towards the edentulous ridge. In the first case, the 3D model and FEA were developed using Autodesk Inventor 2013 software. In the second case, the FEA was done using Autodesk Algor Simulation software. The loading of the model was symmetrically applied, considering the magnitude of the tangential and normal oral forces determined by Las Casas et al. These forces were applied to all the PM1, PM2, M1 and M2 pairs. Each loading case was analysed separately. The results of the two constrain situations are presented graphically, comparatively and show that the amount of the saddle displacement depends on the application area of the mastication force. Maximum displacement was computed at the application of the mastication forces on the M2 and decreases as the force is applied more mesial. The amount of the major connector’s deformation is very little influenced by the site of the force. The largest displacement of the denture was recorded at the distal end of the saddle, with values ​​that depend on the site of the forces. The existence of the rotational movement of the denture’s free end saddles in the sagittal plane, towards the edentulous ridge, changes the values ​​of accumulated stresses in denture during mastication and its Von Mises stress peaks. This analysis can be use to establish the principles of planning and designing the RPD with ball attachments having in mind to minimize the number of repairs caused by fractures of the components.
