The objective was to evaluate and compare single- and two-implant retained overdentures for the rehabilitation of the edentulous mandible. Fifty-six edentulous subjects were eligible for inclusion. Using a random sampling system, a single implant or two implants were placed in the mandible. After 3 months, locator attachments were connected to the implants and the denture delivered with the retentive components incorporated in the denture base. Implant failure and muscle activity were evaluated at the 3-, 6-, and 12-month follow-up examinations...

The prosthodontic treatment of patients with a retrognathic edentulous maxilla should consider the restoration of the lower facial profile and access for oral hygiene. This clinical report describes prosthodontic treatments of a patient with edentulism who presented with repeated fractures of the denture teeth of a maxillary implant-supported complete fixed dental prosthesis (ICFDP) and a mandibular implant-supported overdenture. Considerable plaque accumulation was noted on the ICFDP, which was replaced with an open palatal design implant-supported overdenture...

To assess the implant stability during different stages of healing in an immediate loaded implant soon after extraction. A 73-year-old female came with a chief complaint of bad smell and irritation in her lower front gum region. On examination, she was found to be completely edentulous in the maxillary arch and partially edentulous in the mandibular arch with only the canines present bilaterally. The posterior mandibular ridge was severely resorbed and hence could not be treated with a conventional mandibular complete denture...

BACKGROUND: Total tooth loss (edentulism) can be a debilitating condition, impacting on ability to chew, speak and interact with others. The most common treatment is with complete removable dentures, which may be successful, but in the lower jaw, bone resorption that worsens over time makes denture-wearing difficult. Two dental implants in the mandible to retain the lower denture has been advocated as the gold standard of treatment, but has not been universally provided due largely to financial constraints and also patient fear...

With the development of 3D printing and computer graphics technology, mouth rehabilitation has increasingly adopted digital methods. This research proposes a new method to transform the appearance of facial model after complete denture prosthesis. A feature template with few feature points is first constructed according to the facial muscle anatomy and facial deformation after complete denture prosthesis. Next, the traditional as-rigid-as-possible (ARAP) method is optimised by clustering based on facial muscles...

To tackle a large midline diastema and generalized spacing existing before extraction often poses a challenge to the treating prosthodontist. The situation becomes even more complicated if the patient is a teenager, with multiple missing teeth, associated deep bite and where the jaw bone growth has not yet been completed. Possible treatment options would include a removable prosthesis, a fixed partial denture or an implant supported prosthesis. Treating such cases with a simple removable prosthesis cannot be justified if a deep bite existed which would result in posterior disocclusion...

Severe bone loss in patients with complete edentulism poses a treatment challenge. In fabricating a denture, the stability of the prosthesis must be enhanced by recording the cameo surface within the confines of the physiological position of the cheek and tongue muscles (the neutral zone) and by shaping it accordingly. The treatment of a patient with a completely edentulous maxillary arch and severe maxillary anterior bone loss is described. The cameo surface was recorded within the physiological limits during the fabrication of a complete denture by using transcutaneous electrical nerve stimulation (TENS)...
