(Mosby Inc, 2024-01) Alqutaibi, Ahmed Yaseen; Algabri, Radhwan S; Elawady, Dina; Ibrahim, Wafaa Ibrahim
Abstract Statement of problem: The evidence regarding the application of artificial intelligence (AI) in identifying dental implant systems is currently inconclusive. The available studies present varying results and methodologies, making it difficult to draw definitive conclusions. Purpose: The purpose of this systematic review with meta-analysis was to comprehensively analyze and evaluate articles that investigate the application of AI in identifying and classifying dental implant systems. Material and methods: An electronic systematic review was conducted across 3 databases: MEDLINE/PubMed, Cochrane, and Scopus. Additionally, a manual search was performed. The inclusion criteria consisted of peer-reviewed studies investigating the accuracy of AI-based diagnostic tools on dental radiographs for identifying and classifying dental implant systems and comparing the results with those obtained by expert judges using manual techniques—the search strategy encompassed articles published until September 2023. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to assess the quality of included articles. Results: Twenty-two eligible articles were included in this review. These articles described the use of AI in detecting dental implants through conventional radiographs. The pooled data showed that dental implant identification had an overall accuracy of 92.56% (range 90.49% to 94.63%). Eleven studies showed a low risk of bias, 6 demonstrated some concern risk, and 5 showed a high risk of bias. Conclusions: AI models using panoramic and periapical radiographs can accurately identify and categorize dental implant systems. However, additional well-conducted research is recommended to identify the most common implant systems.
ATTACHMENT VERSUS CLASP RETAINED REMOVABLE PARTIAL DENTURES –A RANDOMIZED CONTROLLED CLINICAL TRIAL
(EDJ, 2019-04) Elawady, Dina Mohamed Ahmed; Ibrahim, Wafaa Ibrahim
Purpose: to compare two retainer designs for free end removable partial dentures (RPDs) by measuring the patient satisfaction, abutment tooth survival, bone height loss and pocket depth. Materials and Methods: Group 1: Fourteen patients receiving attachment-retained RPDs while group 2: Fourteen patients receiving clasp-retained RPDs. The assessment included patient satisfaction, survival of the terminal abutments, bone height loss and pocket depth. All patients were evaluated clinically and radiographically at the time of RPD insertion, twelve months and 24 months thereafter. Mann Whitney U test for independent samples was used for comparison of % change of patient satisfaction. Wilcoxon signed rank test for paired (matched) samples was used within group comparison of patient satisfaction before and after treatment. Survival analysis was done using Kaplan Meier statistics. For bone height, independent t-test was used and student’s t- test was used for pocket depth comparison. Results: There was a significant difference before and after treatment scores in Oral Health Impact Profile-14(OHIP-14), Orofacial Esthetic Scale (OES) and Chewing Function Questionnaire (CFQ) questionnaires in the clasp retained RPD group with P value = (0.001, 0.001 and 0.003) re- spectively. Regarding the attachment retained RPD group, there was a significant difference before and after treatment scores with P value = 0.001 for the three questionnaires. Within group compari- son it was found that there was a significant difference in OHIP-14 (P= 0.002) and OES (P<0.001) while there was no significant difference in CFQ between both groups (P=0.191). There was no statistically significant difference between both groups in terminal abutment survival (P=0.149) and percent change of the mean probing pocket depth from baseline to 24 months (P=0.05). However, regarding the effect of time on bone height change percentage for each group, a significant differ- ence was found between groups at baseline-twenty-four month’s interval (P-value < 0.05). Conclusion: Within the limitations of the present study, all patients have shown improvement in OHRQoL, esthetics and chewing function after treatment with RPDs with better results in the attachment retained RPD. However, regarding the terminal abutment survival, mean probing pocket depth and bone height change, clinically significant better results were revealed in clasp-retained RPD compared to attachment-retained RPDs
Clinical evaluation of implant overdentures fabricated using 3D-printing technology versus conventional fabrication techniques: a randomized clinical trial
(QUINTESSENCE PUBLISHING CO INC, 2021-02) Elawad, Dina Mohamed; Ibrahim, Wafaa Ibrahim; Osman, Reham B
Aim: To evaluate the oral health-related quality of life (OHRQoL) of patients rehabilitated with conventional or 3D-printed implant overdentures. Materials and methods: A randomized clinical trial (RCT) was designed. Twenty-eight completely edentulous participants were randomly allocated into two equal groups. All partici-pants received two implants with ball attachments. Partici-pants in the control group were rehabilitated with conven-tionally manufactured polymethyl methacrylate (PMMA) maxillary complete dentures (CDs) and mandibular implant overdentures, while those in the intervention group received digital light processing (DLP)-printed photopolymerizable PMMA maxillary CDs (NextDent) and mandibular implant overdentures. Follow-up appointments were scheduled at 3, 6, and 12 months where Oral Health Impact Profile 19 (OHI-PEDENT19) data were used to assess the OHRQoL of the par-ticipants. Denture retention was measured using a digital force gauge device. Results: The OHRQoL values were significantly higher (less improvement) in the conventional overdenture group at 6 months (P = 0.02) and 12 months (P = 0.04). A statistically significant difference was found between the mean retention values of the conventional and 3D-printed overdenture groups. For all the follow-up periods, the mean retention val-ues were higher for the 3D-printed overdenture group (P = 0.001). Conclusion: 3D-printed overdentures may represent an alter-native to conventionally fabricated ones. This study repre-sents a stepping stone and proof of concept that support the potential future use of 3D-printed dentures.
Clinical influence of digital vs analog impressions in all-on-4 implant prostheses: a randomized controlled trial
(Quintessenz Verlags GmbH, 2022-05) Elawady, Dina Mohamed; Ibrahim, Wafaa Ibrahim
Aim: To compare the clinical outcomes of conventional and digital implant impressions in all-on-4 mandibular implant prostheses. Materials and methods: Fifty-six participants were randomly stratified into two control groups (Axial Conventional Impression Group [ACIG] and Tilted Conventional Impression Group [TCIG]), and two test groups (Axial Digital Impression Group [ADIG] and Tilted Digital Impression Group [TDIG]). Conventional pick-up and digital impressions were made for each group, respectively. Participants in ACIG and ADIG received four axial implants, and those in TCIG and TDIG received two anterior axial and two distal tilted implants. All participants received all-on-4 mandibular prostheses and maxillary complete dentures. Implant survival, prosthetic complications, and marginal bone loss were recorded at 6, 12, and 24 months. Data were statistically described in terms of mean +/- standard deviation. Results: After 24 months, the implant survival rate was 100%. A significant difference in bone loss was shown between ACIG and ADIG at 6, 12, and 24 months, with P = 0.647, 0.821, and 0.505, respectively. An insignificant difference in bone loss was shown between TCIG and TDIG at 6 ,12, and 24 months, with P = 0.671, 0.935, and 0.687, respectively. No significant difference was shown in prosthodontic complications between all groups throughout the follow-up period. Conclusions: The digital impressions showed clinically better implant survival, stable peri-implant marginal bone level, and reasonable prosthodontic complications. The present study represents a steppingstone and proof of concept that supports the routine clinical use of digital impressions, especially in a post-COVID-19 world.
Dental implant planning using artificial intelligence: A systematic review and meta-analysis
(Elsevier Inc, 2024-04) Alqutaibi, Ahmed Yaseen; Algabri, Radhwan; Ibrahim, Wafaa Ibrahim; Alhajj, Mohammed Nasser; Elawady, Dina
Statement of problem: Data on the role of artificial intelligence (AI) in dental implant planning is insufficient. Purpose: The purpose of this systematic review with meta-analysis was to analyze and evaluate articles that assess the effectiveness of AI algorithms in dental implant planning, specifically in detecting edentulous areas and evaluating bone dimensions. Material and methods: A systematic review was conducted across the MEDLINE/PubMed, Web of Science, Cochrane, and Scopus databases. In addition, a manual search was performed. The inclusion criteria consisted of peer-reviewed studies that examined the accuracy of AI-based diagnostic tools on dental radiographs for dental implant planning. The most recent search was conducted in January 2024. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to assess the quality of the included articles. Results: Twelve articles met the inclusion criteria for this review and focused on the application of AI in dental implant planning using cone beam computed tomography (CBCT) images. The pooled data indicated an overall accuracy of 96% (95% CI=94% to 98%) for the mandible and 83% (95% CI=82% to 84%) for the maxilla in identifying edentulous areas for implant planning. Eight studies had a low risk of bias, 2 studies had some concern of bias, and 2 studies had a high risk of bias. Conclusions: AI models have the potential to identify edentulous areas and provide measurements of bone as part of dental implant planning using CBCT images. However, additional well-conducted research is needed to enhance the accuracy, generalizability, and applicability of AI-based approaches.
Palatal vault configuration and its influence on intraoral scan time and accuracy in completely edentulous arches: a prospective clinical study
(The Korean Academy of prosthodontics, 2024-08) Elawady, Dina Mohamed Ahmed; Ibrahim, Wafaa Ibrahim; Ghanem, Radwa Gamal; Osman, Reham Bassuni
PURPOSE. The aim of this prospective clinical study was to compare the influence of palatal vault forms on accuracy and speed of intraoral (IO) scans in completely edentulous cases. MATERIALS AND METHODS. Based on the palatal vault form, participants were divided into three equal groups (n = 10 each); Class I: moderate; Class II: deep; Class III: flat palatal vault. A reference model was created for each patient using polyvinylsiloxane impression material. The poured models were digitized using an extraoral scanner. The resultant data were imported as a solid CAD file into 3D analysis software (GOM Inspect 2018; Gom GmbH, Braunschweig, Germany) and aligned using the software’s coordinate system to determine its X, Y, and Z axes. Five digital impressions (DIs) of maxilla were captured for each patient using an intraoral scanner (TRIOS; 3Shape A/S, Copenhagen, Denmark) and the resultant Standard Tessellation Language (STL) scan files served as test models. Trueness was evaluated by calculating arithmetic mean deviation (AMD) of the vault area between reference and test files while precision was evaluated by calculating AMD between captured scans to measure repeatability of scan acquisition. The scan time taken for each participant was also recorded. RESULTS. There was no significant difference in trueness and precision among the groups (P =.806 and.950, respectively). Average scan time for Class I and III palatal vaults was 1 min 13 seconds and 1 min 37 seconds, respectively, while class II deep palatal vaults showed the highest scan time of 5 mins. CONCLUSION. Palatal vault form in edentulous cases has an influence on scan time. However, it does not have a substantial impact on the accuracy of the acquired scans.
