Edentulous Jaw
Conditions
Brief summary
complete denture wearers struggle to eat well with their dentures due to poor denture retention, stability, and occlusal disharmony. So, the current study protocol aims to compare the occlusion/ disocclusion time in immediately loaded implant retained overdentures supported by two interforaminal implants; splinted versus non splinted dental implants compared to the conventional complete denture.
Detailed description
The gold standard treatment for completely edentulous patients is a removable complete denture, which satisfies patients functional and aesthetic requirements at a low cost. However, the main problem associated with a complete denture is the instability of the complete removable denture, especially the mandibular one. Implant-assisted overdentures over two or three implants are used as a treatment option to increase stability, function, and retention of the denture at a reasonable cost. The immediate loading protocol allows the placement of temporary restoration on the day of implant placement surgery. Pierluigi Mondani pioneered intraoral welding in the early 1970s as an approach to load patients immediately with resin prosthesis and weld titanium implants to a titanium bar in their mouths. The technique of intraoral welding provides rigid splinting in cases of immediate implant loading. Occlusal loads and stability of occlusion are important to consider in the immediate loading of implants to avoid implant biomechanical failures, marginal bone loss, or even complete loss of osseointegration. Quantitative analyzers like t-scans, which are pressure-sensitive films, and virtual technology give a precise method of assessing the sequence of time and occlusal contact force magnitude by converting qualitative data into quantitative parameters. So, the current study protocol aims to compare the occlusion/ disocclusion time in immediately loaded implant retained overdentures supported by two interforaminal implants; splinted versus non splinted dental implants compared to the conventional complete denture.
