Purpose: The present retrospective clinical study aimed to evaluate and compare the clinical and radiographic parameters, complications, and satisfaction in patients who received fixed prostheses supported by narrow-diameter implants (NDIs) in the anterior and posterior jaw. Methods: Patients aged ≥30 years who had NDI-supported fixed prostheses in the anterior or posterior region of either jaw for at least 2 years were included. Complications such as chipping of the crown; loosening or fracture of the screw, crown abutment, or implant; and loss of retention were recorded. Clinical peri-implant outcomes and crestal bone loss (CBL) were measured. A questionnaire was used to record responses regarding the aesthetics and function of the fixed restorations. Analysis of variance was used to assess the significance of between-group mean comparisons. The log-rank test was performed to analyze the influence of location and prosthesis type on technical complications. Results: Seventy-one patients (mean age: 39.6 years) provided informed consent with a mean follow-up duration of 53 months. Only bleeding on probing showed a statistically significant difference between NDIs in the anterior and posterior regions. The complication rate for NDIs in the posterior region was significantly higher than that for NDIs in the anterior region (P=0.041). For NDIs, CBL was significantly higher around splinted crowns than single crowns (P=0.022). Overall mean patient satisfaction was 10.34±3.65 on a visual analogue scale. Conclusions: NDIs in the anterior and posterior jaws functioned equally well in terms of periimplant soft and hard tissue health and offered acceptable patient satisfaction and reasonable complication rates.

문제 정의
This study focused on the comparative analysis of NDIs placed in the anterior and posterior regions. Their clinical peri-implant parameters, including plaque levels, bleeding scores, PD, and radiographic evidence of bone loss, were recorded.
제안 방법
All details regarding NDIs and RDIs were obtained from the records saved in the database. All NDIs and RDIs were screened to determine the depth of placement, a total number of implants, implant loading, and duration of implants in service, implant design, and implant length and diameter. The restoration type was also determined at the follow-up assessment.
All clinical measurements were taken at 6 sites of the NDIs and reported as mean percentages per individual. All clinical parameters were measured using a manual periodontal probe (UNC-15, Hu-Friedy, Chicago, IL, USA).
All clinical peri-implant assessments were conducted by a single and calibrated examiner (Mohammed Alrabiah). Kappa scores were used to estimate probing depth (PD) before detailed clinical measurements were performed.
Normality testing was conducted using the Shapiro-Wilk test before performing any further statistical tests. For all dependent variables, including clinical peri-implant parameters and CBL, analysis of variance was used to assess the significance of between-group comparisons of mean values. The Dunn test was used for multiple comparisons.
Their clinical peri-implant parameters, including plaque levels, bleeding scores, PD, and radiographic evidence of bone loss, were recorded. In addition, technical complication rates and patient satisfaction were evaluated. The results of the present retrospective study suggest that clinical and radiographic parameters showed statistically similar outcomes during the follow-up period.

9 months, respectively. The implant-supported fixed restorations included a total of 85 screw-retained and 29 cement-retained restorations for NDIs and 72 screw-retained and 49 cement-retained restorations for RDIs, while 46 NDIs and 52 RDIs supported single crowns and 68 NDIs and 69 RDIs supported splinted restorations.
These factors may contribute to the complication rate and thereby reduce the overall clinical success of NDIs placed in the posterior region. Therefore, the present retrospective clinical study aimed to evaluate and compare the clinical and radiographic parameters, complication rates, and patient satisfaction levels of fixed prostheses supported by NDIs placed in the anterior and posterior regions.
대상 데이터
A total of 114 NDIs (36 in the maxilla and 78 in the mandible) and 121 RDIs (48 in the maxilla and 73 in the mandible) were examined, of which 61 NDIs and 74 RDIs were implanted in the anterior jaw, while 53 NDIs and 47 RDIs were implanted in the posterior region. All implants were bone-level platform-switched implants with moderately rough surfaces that were either 10 mm or 12 mm in length and that had diameters of 3.3 mm (for the NDIs) or 4.0 mm (for the RDIs). The NDIs and RDIs had mean loading periods of 3.
Patients aged ≥30 years who had NDI- and RDI-supported fixed prostheses in the anterior or posterior region of either jaw for a minimum duration of 2 years were selected for the study.

성능/효과
The mean follow-up duration was 53 months. A total of 114 NDIs (36 in the maxilla and 78 in the mandible) and 121 RDIs (48 in the maxilla and 73 in the mandible) were examined, of which 61 NDIs and 74 RDIs were implanted in the anterior jaw, while 53 NDIs and 47 RDIs were implanted in the posterior region. All implants were bone-level platform-switched implants with moderately rough surfaces that were either 10 mm or 12 mm in length and that had diameters of 3.
Around anterior NDIs, the mean percentages of sites for which “yes” was recorded in the assessments of PS and BOP were 18.2% and 23.8%, respectively, while these values around posterior NDIs were 26.5% and 35.1%, respectively.
Some noticeable limitations are present in this study. First, survival analysis using advanced statistical methods such as Kaplan-Meier analysis was not performed. Additionally, with the strict eligibility criteria imposed, the outcomes may not translate to other cohorts, including tobacco smokers and individuals with systemic disorders such as uncontrolled diabetes mellitus.
None of the clinical parameters displayed statistically significant differences between NDIs and RDIs or between the anterior and posterior regions (P>0.05), with the exception of BOP, for which a statistically significant difference was observed between the anterior and posterior regions for NDIs.
01). The log-rank test showed that the CBL of NDIs was statistically significantly higher around splinted crowns than around single crowns (P=0.022) (Table 3).
후속연구
Finally, a limited number of NDIs were studied in the maxillary jaw, even though the maxilla and mandible differ in their bone mineral density, suggesting a potentially different outcome in mandibular NDIs. Therefore, future studies should be undertaken to confirm the clinical efficacy of NDIs in maxillary jaws compared to mandibular jaws.
