Abstract
Implant therapy is gaining immense importance in people presenting with missing teeth due to its increased life expectancy. There is a high concern regarding the link between obesity and peri-implant diseases. The aim of this study was to assess the peri-implant health parameters among the obese and non-obese South Indian population. The cross-sectional study was conducted in Department of Implantology, Saveetha Dental College and Hospitals Chennai, India among 859 patients who reported between January 2022-November 2022 and had a minimum of single implant in function for at least 1 year after crown cementation. Among 859 patients, 428 were non-obese (Group A) and 431 were obese (Group B). Patient's data including the menopausal status was recorded. Clinical parameters including peri-implant probing depth (PPD), clinical attachment level (CAL) and radiographic parameter including alveolar bone level (ABL) was recorded and compared between both the groups using independent t-test. The mean PPD among non-obese and obese population were 2.58 ± 0.03 and 4.09 ± 0.04, respectively. The mean CAL among non-obese and obese population were 2.87 ± 0.02 and 4.19 ± 0.01, respectively. The mean ABL among non-obese and obese population were 2.06 ± 0.01 and 3.17 ± 0.03, respectively. Independent t-test revealed there was statistically significant difference in PPD (P = 0.04), CAL (P = 0.05) and ABL (P = 0.04). The present study suggests that the obese individuals demonstrated high peri-implant probing depth, clinical attachment loss and alveolar bone loss as compared to non-obese individuals.

Influence of risk factors on the long-term survival of oral rehabilitation with extra-narrow implants: a retrospective study. J Appl Oral Sci 2022; 30:e20220089. [PMID: 35920448 PMCID: PMC9365337 DOI: 10.1590/1678-7757-2022-0089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 06/22/2022] [Indexed: 11/22/2022] Open
Abstract
Objective This study aimed to retrospectively collect clinical data to evaluate the influence of possible risk factors on the long-term success of implant treatment with extra-narrow (2.9 mm diameter) implants in a daily dental practice setting. Methodology Data were collected from records of patients who received at least one extra-narrow implant from 2012 to 2017, regarding implant survival, prosthesis survival, patient characteristics, and implant characteristics. The association between the dependent variables “implant survival”, “prosthesis survival,” and “adverse events” related to patient and implant characteristics was statistically evaluated by chi-square tests. Moreover, implant and prosthesis survival were analyzed by Kaplan-Meier survival curves. Results The sample was constituted of 58 patients (37 women and 21 men) with a mean age of 54.8 years old (SD: 12.5), followed up for up to eight years. In total, 86 extra-narrow implants were placed within this sample. Four implants were lost, resulting in an implant survival rate of 95.3%. A total of 55 prostheses were inserted and only one (1.8%) was lost, resulting in a prosthesis survival rate of 98.2%. The mean implant and prosthesis survival time was, respectively, 7.1 years and 6.3 years, according to the Kaplan-Meier survival analysis. A correlation was found between smoking and implant loss, which makes implant loss eight times more likely to occur in smokers than non-smokers. A significant association was also found between prosthesis loss and previous need of prosthesis repair. However, it was not considered clinically relevant. No association was found between the occurrence of adverse events and later implant or prosthesis loss. Conclusion High implant and prosthesis survival rates were found in the long term for treatment with extra-narrow implants. Moreover, a significant correlation between smoking and implant loss was observed.

Abstract
Narrow‐diameter implants (≤3.5 mm) have been proposed to address the challenge of implant placement in cases of insufficient bone quantity, thin alveolar crest, and small cervical diameter teeth replacement The aim of this study is to report one‐year outcomes of extra‐narrow implant rehabilitation of maxillary lateral incisors, due to agenesis, in a young adult that presented sites with reduced mesiodistal and buccolingual dimensions. A 26‐year‐old male patient in need of fixed‐implant supported prostheses due to the absence of permanent maxillary lateral incisors and with limited space, was submitted to surgery to receive two 2.9 mm hybrid Morse taper connection implants with hydrophilic surfaces. Immediate loading was applied by means of insertion of provisional prostheses, which were replaced for all‐ceramic prostheses 12 months after surgery. The 1 year follow‐up showed clinical and radiographic success of extra‐narrow implant rehabilitation. Also, both regions presented good evolution of peri‐implant esthetics, as assesses using the pink esthetic score, with improvements at 4 months follow‐up and reaching high scores 12 months after surgery. Although the prosthetic rehabilitation of maxillary lateral incisors is challenging due to limited space for the insertion of implants, the clinical case suggests that the use of extra‐narrow Morse Taper implants with hybrid design and hydrophilic surface is a reliable alternative, presenting good outcomes regarding hard and soft tissue and it is a versatile solution or immediate loading procedure. Further studies are needed to confirm extra‐narrow implant predictability.

Implant-prosthetic rehabilitation of patients with severe horizontal bone deficit on mini-implants with two-piece design-retrospective analysis after a mean follow-up of 5 years. Int J Implant Dent 2021; 7:71. [PMID: 34318379 PMCID: PMC8316513 DOI: 10.1186/s40729-021-00353-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 05/05/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND As a consequence of tooth loss due to trauma or extraction, a reduced alveolar crest volume limits the deployment of standard implants in certain patient cases. For this reason, minimal-invasive treatment with mini-dental implants (MDI) might be an option to allow implant treatment even in cases with severe horizontal bone loss without augmentation measures. The aim of this retrospective cohort study was to investigate clinical and radiological implant, as well as patient-related parameters after treatment with MDI. RESULTS Clinical and radiological records of 19 female (82.6%) and 4 male patients (17.4%) (N = 23), who received 52 mini-dental implants with a two-piece design in a single surgical center between November 2011 and October 2018, were retrospectively analyzed. Implants were submitted to conventional loading on different types of screwed superstructures. Crestal bone loss was measured on standardized periapical radiographs. Patient-related outcome parameters (PROMs) were recorded during follow-up period. Mean clinical and radiological follow-up was 69.6 months (5.8 years) and 51.6 months (4.3 years), respectively. Three implants were lost in two patients, leading to an implant survival rate of 94.2%. Mean radiological crestal bone loss was 1.6 mm. Both amount of peri-implant recession and crestal bone loss were significantly correlated (r = 0.65; p < 0.001). Likewise, a significant correlation was observed between deeper probing depths and increased peri-implant bone loss (r = 0.41; p = 0.012). Alveolar ridges with a reduced alveolar crest width were significantly correlated with higher peri-implant bone loss as well (r = - 0.33; p = 0.011). No prosthetic complications were reported during follow-up. Extent of midfacial recession and papilla height loss had a significant negative impact on most of the PROMs. CONCLUSIONS Treatment with MDI seems to be a successful alternative treatment option, especially for elderly patients with reduced crest width at implant sites. Due to the good clinical results and high survival and success rates, this treatment option was associated with high patient satisfaction. Despite the promising results, particular consideration should be given to appropriate treatment planning in these patients due to the strong correlation between peri-implant soft-tissue parameters, crestal bone loss, and reduced alveolar crest width.

Abstract
BACKGROUND The authors hypothesized that there is no difference in the primary stability (PS) of multiple condensing thread design (MCTD) implants placed in simulated type-IV bone with and without using osteotomes. PURPOSE This in vitro study assessed the PS of narrow-diameter dental implants with MCTD placed in simulated soft (type-IV) bone with and without using osteotomes. MATERIALS AND METHODS Sixty MCT-designed implants (diameter: 3.0 mm; length: 11.5 mm) were placed using 800 rpm drilling speed in cellular rigid polyurethane foam bone-blocks that simulated type-IV bone. Prior to placement, the implants were divided into three groups (20 implants per group) depending upon the protocol used for osteotomy preparation-Group-1: Conventional drilling (CD); Group-2: CD followed by osseous condensation using a chisel-shaped tapered osteotome with maximum diameter of 3 mm; and Group-3: CD followed by osseous condensation using a cylindrical osteotome with maximum diameter of 3 mm. Abutments were connected to all implants and PS was recorded using resonance frequency analysis (RFA) and the periotest (PTV). Group comparisons were performed using analysis and Bonferroni post-hoc adjustment tests. Level of significance was set at P < .05. RESULTS There was no statistically significant difference in the RFA values for the MCT-designed implants placed in groups 1, 2, and 3 (59.85 ± 0.72, 59.67 ± 0.76 and 59.42 ± 0.92, respectively). There was no statistically significant difference in the PTV values for MCT-designed implants in groups 1, 2, and 3 (1.655 ± 0.82, 1.405 ± 0.57, and 1.078 ± 0.63, respectively). CONCLUSION The MCTD implants with narrow diameters have a high PS in artificial soft bone in vitro. Due to the condensation effect of the thread design, there is no need for additional condensation of the peri-osteotomy bone in order to improve implant stability.

Peri-implant soft tissue status and crestal bone loss around immediately-loaded narrow-diameter implants placed in cigarette-smokers: 6-year follow-up results. Clin Implant Dent Relat Res 2020; 22:220-225. [PMID: 32157803 DOI: 10.1111/cid.12893] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 02/18/2020] [Accepted: 02/25/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND It is hypothesized that in the long-term, soft tissue inflammation (reflected by increased scores of peri-implant probing-depth [PD]) and crestal bone loss (CBL) is higher in cigarette-smoker than nonsmokers with narrow diameter implants (NDIs). PURPOSE The aim of the present 6-years' follow-up clinical observational study was to compare the peri-implant soft tissue inflammatory parameters (plaque index [PI], gingival index [GI], and PD) and CBL around immediately-loaded NDIs placed in cigarette-smokers and nonsmokers. MATERIALS AND METHODS In all groups, peri-implant GI, PI and PD were measured on six sites (distolingual/palatal, mesiolingual/palatal mesiobuccal, distobuccal, midlingual/palatal, and midbuccal) per implant. The CBL was gauged on digital bitewing x-rays, which were standardized using the long cone paralleling technique. CBL was demarcated as the vertical distance from 2 mm below the implant-abutment connection to the most crestally-positioned alveolar bone. RESULTS All study-participants were male. Twenty-six cigarette smokers and twenty-five nonsmokers were included. The mean age of cigarette-smokers and nonsmokers was 45.5 ± 10.3 and 47.4 ± 9.4 years, respectively. Cigarette-smokers had a smoking history of 10.6 ± 0.4 pack years. Family history of tobacco usage was more often reported by cigarette-smokers (57.7%) than nonsmokers (20%). All cigarette-smokers and nonsmokers were aware that smoking is a risk-factor of loss of implant. Three (11.5%) of cigarette-smokers reported that they have attempted to quit smoking and 76.9% of cigarette-smokers (n = 20) reported that they had no intention to quit smoking in the future. The peri-implant P-I (P < .01), PD (P < .01) and mesial (P < .01), and distal (P < .01) CBL were significantly high in cigarette-smokers compared with nonsmokers. There was no statistically significant difference in GI among the groups. CONCLUSION Cigarette-smoking enhances peri-implant soft tissue inflammation and increases CBL around immediately-loaded NDIs.

Abstract
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 peri-implant soft and hard tissue health and offered acceptable patient satisfaction and reasonable complication rates.
