About this study
Official title: Clinical Outcome of Subcrestal Short Implant Versus Crestal Standard Length Implant to Retain Kennedy Class 1 Removable Partial Denture: A Split-mouth Study
Objective: To report the implant survival rates, clinical, and radiographic outcomes of subcrestal short implant versus crestal standard length implant supported removable partial denture (RPD).
Read the detailed description
30 individuals with at least 2 adjacent missing teeth bilaterally were included.to support class Ι RPD with conventional loading protocol were chosen for this research. Each participant received 2 implants in a split mouth design, one side received 1 subcrestal short implant and the contralateral side crestal standard length implant. Plaque index (PI), bleeding on probing (BOP), probing depth (PD), radiographic crestal bone level (CBL) and implant survival rate were evaluated. at implant placement (T0), restoration delivery (T1), and 3-year follow-up after loading (T2). MBL was calculated as the change in distance from the implant-abutment interface to the first radiographically visible bone-implant contact. A repeated-measures mixed ANOVA followed by a paired Student's t-test with the Bonferroni correction was used for statistical analysis. p < 0.05 was considered statistically significant

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Titanium dental implant (Conical SPI, Vitronix, Italy), Medical device that interfaces with the jawbone to support a dental prosthesis.Procedure or surgery
Placement of titanium dental implant to retain and support Kennedy class 1 removable partial denture (RPD).The implant fuses with the bone through a process called osseointegration.
| Study group | Role | What they receive |
|---|---|---|
| Subcrestal short implant | Active comparator | Evaluation the amount of bone loss after one, two, and three years of function. Receives: Procedure: Titanium dental implant (Conical SPI, Vitronix, Italy), Medical device that interfaces with the jawbone to support a dental prosthesis. |
| crestal standard length implant | Active comparator | Evaluation the amount of bone loss after one, two, and three years of function. Receives: Procedure: Titanium dental implant (Conical SPI, Vitronix, Italy), Medical device that interfaces with the jawbone to support a dental prosthesis. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Bone loss
Evaluation of crestal bone loss around implants will be performed by periapical digital radiograph using parallel technique to avoid distortion or elongation to the image.
Measured: 3 years
Secondary outcomes (2)
Plaque index (PI)
Evaluation of PI around implants were assessed by using a numerical recording of BI (present = 1; absent = 0), PI (present = 1; absent = 0), as well as PD. With the use of a plastic periodontal probe (Hu-Friedy, Chicago, Illinois).
Measured: 3 years
Bleeding on probing (BOP)
Evaluation of BOP around implants were assessed by using a numerical recording of BOP (present = 1; absent = 0), PI (present = 1; absent = 0), as well as PD. With the use of a plastic periodontal probe (Hu-Friedy, Chicago, Illinois).
Measured: 3 years

Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Bone loss (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2024; AzTrials last refreshed its copy on 8 Nov 2026.
