“…The mechanical and behavioral factors of stress (amplitude, direction, rate, and frequency) affect bone remodeling, particularly in the neck region (Cehreli et al, 2004). Thus, cylindrical implants may require a higher insertion torque to achieve primary stability, and if exceeded by 50 Ncm may potentiate MBL (Nandini, et al, 2022;Stoilov, et al, 2023). , demonstrated that cylindrical implants showed a slight increase in MBL compared to conical implants, but not in a statistically significant way.…”

Purpose: The purpose of this systematic review was to critically evaluate the existing literature and answer the question, “Which implant format and prosthetic platform promotes the least cervical resorption?”. Material and method: SCOPUS, PubMed/Medline, Web of Science, EMBASE, Lilacs, and Google Scholar databases were searched in September 2023. Results: The database search resulted in 2850 articles. Of the 12 articles selected for full reading, 2 remained in this systematic review. There is a lack of information to form an opinion and to perform statistical analysis of the data, so descriptive analysis was performed. Conclusions: Based on the studies included in this systematic review, the implant shape influences primary stability and osseointegration, but it is not yet possible to relate it directly to POC. However, the type of prosthetic platform has a direct influence. In addition to the type of prosthetic platform used, the various characteristics related to the shape of the implant must be considered to maintain satisfactory bone levels.

“…The success of dental implants is directly influenced by the level of primary stability after implant placement 15 , and the implant macrostructure plays an important role in achieving primary stability 7 , 12 . The shape of implants and the thread configurations influence this parameter, as demonstrated in previous studies in which tapered implants presented greater stability than cylindrical implants 8 , 12 , 15 . The implants used in the current study have a hybrid macrostructure in which there is an association of a cylindrical shape in the coronal portion and a tapered shape in the lower portion with a double-threaded design, and this type of implant macrostructure has also been shown to present superior stability to cylindrical implants with single-threaded design 7 , 16 .…”

This split-mouth randomized controlled trial aimed to evaluate the primary and secondary stability of hybrid implants with different thread configurations and hydrophilic surfaces. Twenty patients with a partially edentulous maxilla were selected. These patients received two types of implants with the same hydrophilic surface: CTP group: Cylindrical-Tapered implant with perforating threads; CTH: Cylindrical-Tapered implant with hybrid threads configuration (perforating and condensing threads). The primary and secondary stability parameters were measured by insertion torque and resonance frequency analysis at the time of implant placement and 7, 28, 56, and 90 days after the surgical procedure. The paired t-test was used to compare the data on the implant's stability between the groups. The statistical analysis was performed with a confidence level set at 95%. It was found that the implants in the CTH group presented higher primary stability values at the time of implant placement, due to the higher ISQ (63.61 ± 9.44 vs. 40.59 ±7.46) and insertion torque (36.92 ± 16.50 Ncm vs. 28.00 ± 14.40 Ncm), than the implants in the CTP group. The CTH group presented higher ISQ values in all follow-up periods: 7 days (68.67 ± 7.60 vs. 41.55 ± 9.07), 28 days (68.61 ± 5.98 vs. 47.90 ±13.10), 56 days (74.09 ± 3.96 vs. 55.85 ± 13.18), and 90 days (75.45 ± 4.02 vs. 63.47 ± 6.92) after implant placement. Hybrid implants with perforating and condensing threads demonstrated greater stability than hybrid implants with only perforating threads.

“…Although the studies in the literature are inconclusive regarding the survival/success rate of different implant types (tapered vs. cylindrical), the connection type seems to have an impact on long-term stability, especially the morse-taper connection [ 56 ]. The primary stability of tapered implants has been demonstrated to be higher than that of cylindrical ones [ 57 ], which can have a direct impact on the marginal bone level if loaded immediately [ 58 ]. Even though our findings are similar to other studies, we cannot neglect the risk of bias due to the large difference in implant numbers on the two used systems and the observational nature of our study.…”

The objective of the present study was to evaluate the 5-year outcome of dental implant therapy and assess the survival, success, and biological and technical complications. A periodontal and prosthetic-oriented evaluation was conducted on the variables that can influence the long-term predictability of implant therapy. A total of 615 patients and 1427 dental implants from a private clinic (MedArtis Dent, Cluj-Napoca, Romania) were enrolled in the study. The study was a longitudinal cohort with data collected retrospectively from physical/digital dental records in combination with a cross-sectional clinical/radiological examination. Results showed that periodontal diagnosis at baseline had a significant impact on the marginal bone loss prediction. Data showed that the cylindrical implant with an internal 45° medium taper connection experienced a higher rate of bone resorption compared to the tapered implant with the 5° internal connection. Screw-retained restorations and overdentures showed a statistical decrease in the marginal bone level height when compared to the cemented restorations. Data from our study suggest that not only is there a powerful association between recall visits and the rate of complications in dental implant treatment, but a lack of professional maintenance predicts a higher bone level loss during the 5-year interval.
