Survival Rate of 2 Implant-supported Short-span Fixed Partial Dentures

NCT06447792 | Recruiting

• 1 other identifier: ADMNF-0020524
• Study Type: observational
• Target: 60
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Implant Complication; Bone Loss

Outcome Measures

Primary Outcomes (1)

• Implant survival

  The implant is present at the follow-up examination but its condition is not specified.

  3 years

Study Arms (3)

Group 1

immediately placed implants with a delayed loading protocol. Loading was performed after 3 months.

Other: Loading protocol

Group 2

immediately placed implants with a progressive loading protocol. Loading was performed after 5 weeks.

Other: Loading protocol

Group 3

immediately placed implants with an immediate loading protocol. The day of the surgery was also the day of loading.

Other: Loading protocol

Interventions

Loading protocol OTHER

The prosthetic restoration and functional loading of the dental implant.

Group 1; Group 2; Group 3

Eligibility Criteria

• Age: 25 Years - 65 Years
• Sex: all
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

People over 25 and less than 50 years

You may qualify if:

• 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

You may not qualify if:

• 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.
