About this trial
Implant supported superstructure is necessary for long term success and durability of the implant itself in terms of stresses distribution and fracture strength capability.1 Stresses falling on an implant are too much greater than those applied on a tooth structure with a periodontal ligament offering a degree of elasticity. The important mechanical and physical properties of materials used for the fabrication of dental prostheses include adequate flexural and tensile strength and modulus of elasticity, maximum fracture resistance, optimal bond strength and adequate polishability.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
fully dentulous people over 25 who complained of the mobility of 4 mandibular incisor teeth, or partially dentulous people who missed 2 mandibular central incisor teeth and had periodontally affected the neighboring lateral incisor teeth.
These individuals were subsequently treated with 2 implants supporting FPDs and following a delayed, progressive, or immediate loading protocol
Class 0 or 1 bone defects after tooth extraction, were only included in the study
The medical records included data regarding implant type, width, and length, surgical procedure, annual hygienist treatments, radiographs, and implant insertion date
Disqualifiers
had less than 1 years of follow-up, had incomplete restorative or surgical data, had non-diagnostic radiographs, had more or less than 4 unit fixed partial denture
patients did not present for annual follow-up visits to evaluate oral hygiene measures or treat mechanical or technical complications.
Individuals with bone defects class 2, 3, 4, or 5 after mandibular lateral incisor tooth extraction were also excluded.
