Active clinical trials for "Mouth, Edentulous"

This study aims to evaluate the treatment with single implant overdenture for the edentulous mandible. The investigators hypothesize that treatment with lower overdenture retained by a single implant appears to have satisfactory effectiveness as a treatment for patients with specific conditions (such as maladaptive patients), with the advantages of simplicity and greater immediate benefits when compared to the conventional full denture, improving the retention and stability of the denture and better oral-related quality of life.

The result of the study will demonstrate that the functional activity of maxillofacial area with edentulous posterior bounded spaces recovers more effectively in patients treated with restorations on implants comparing to patients treated with fixed dentures.

Diabetes Mellitus (DM) is a recognized factor affecting implant complication rates, including peri-implantitis and peri-implant bone loss, and the apico-coronal position of implants seems interfere on the conditions of peri-implant tissues. However, the influence of the vertical implant position in type 2 diabetics (T2DM) is unclear. This split-mouth randomized controlled trial evaluated the impact of implants of machined-collar placed at crestal level or supracrestally in T2DM rehabilitated with implant-retained overdentures on the clinical, tomographic and immunoinflammatory peri-implant outcomes after implant loading.

The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by a single implant. The study hypothesis is that SIMO is more effective but more costly than the conventional denture, though this incremental cost is relatively low for the offered effectiveness in terms of clinical and patient-reported outcomes.

The objective of the study is to test the efficacy on bone formation of Straumann Bone Ceramic as a grafting material applied in buccal bone dehiscences on simultaneously placed oral implants.

This study aims to test the combined effects of different loading protocols and surgical approaches on clinical and patient-reported outcome measures (PROMs) following the use of four mini implants for mandibular overdenture retention. The main study hypotheses are: There are significant improvements in PROMs following implant intervention compared to baseline measures; Immediately loaded mini implants have similar failure rates compared to mini implants receiving a delayed 6-week protocol. Flapless surgery has similar post-insertion outcomes compared to flapped surgery.

Since the teeth loss leads to disability & impairment, and teeth restoration lead to improvement in the life quality throughout the oral health improvement. The acceptable function of a complete denture on great extent depends on impression technique which includes the maximum coverage of denture supporting areas and making a combination of managing movable soft tissues along with different kinds of impression materials and techniques for accurate reproduction of oral foundation. Border molding considered to be as an important step in the in complete denture fabrication, since the retention of complete dentures depend on several factors, as the biological, physical and mechanical, these factors could be achieved by mean of an accurate border molding followed by an accurate final impression. The border molding technique is the shaping of the border areas of a custom impression tray by manual or functional manipulation of the tissue adjacent to the borders in order to duplicate the size and contour of the vestibule resulting in maintains of the peripheral seal during function. This property causes the border molding process to require twenty-four insertions, namely eight in the maxilla and sixteen in the mandible causing long working time and discomfort in patients. Hence, the material used for this technique should provide optimum working time, have adequate body, and permit the correction of border moulding by additions. However additions if made to a single step border moulded material would again introduce all the disadvantages that are associated with sectional moulding Single-step border molding is considerably more straightforward than sectional border molding owing to the reduced number of tray insertions. This technique is usually used with elastomeric impression materials, which may not provide sufficient time to mold and record the peripheral tissues of the denture bearing area. The present technique uses light polymerizing tray material for molding tray borders, offering extended working time. This is advantageous for operators with less experience, such as dental school students. Furthermore, correction of border molding is possible with the addition of new material. The technique uses materials that are readily available,and no special armamentarium is required.

Introduction: One major complaint frequently voiced by complete denture wearers is denture retention. Conventional denture disadvantage is heat-curing resin deformation. In addition, the pack and press technique that is still more common, residual stresses that occur at the time of packing are released when the material is removed from the flask, causing the resin to shrink, and this shrinkage is cited as a cause of poor fit of the denture base, In the field of prosthetic dentistry, the ability of additive manufacturing to fabricate prosthetic devices based on CAD data influences the overall quality, the mechanical properties of printed parts, the total cost and the manufacturing time. The milling process wastes large quantities of denture base material, and more recent three-dimensional (3D) prototyping promises a more sustainable additive approach by using less denture resin. However, no clinical reports have been published regarding the accuracy of the mucosal surface or denture retention for denture fabricated using conventional techniques compared to those fabricated using additive manufacturing. Aim of the study: Investigate the effect of two techniques of complete denture manufacturing (conventional and 3D printed) on denture retention, trueness (accuracy), and satisfaction. Methodology: Twenty patients will be selected from the outpatient clinic and will be divided into 2 groups, group A for conventional dentures and group B for 3D printed dentures, retention for the two groups will be measured at 0,1 and 3 months, and patient satisfaction will be recorded, and accuracy of the denture base will be measured on the software. The results will be tabulated and statistically analyzed using the SPSS program.

The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by one and two implants and the mandibular fixed prosthesis retained by four implants, based on a randomized clinical trial.

This is a three-armed randomized controlled clinical trial aiming the estimation of dimensional alveolar bone changes after insertion of post-extraction implants through 3 different surgical techniques: open flap, open flap and grafting, flapless.
