ABSTRACT Aim The aim of this nonrandomized controlled preliminary clinical trial was to compare treatment using short and conventional implants in the posterior region of the mandible after prosthesis installation by means of clinical, resonance frequency, and radiographic analyses. Materials and methods A total of 10 patients with 40 dental implants already installed were included in this study. Four implants were installed for each subject, in which the length of the implants (short and conventional) was distributed according to the reminiscent alveolar bone in the left and right side of the mandible. All implants received splinted prosthesis after the osseointegration period. Analyses were performed immediately after prosthesis installation (T1), and 3 (T2) and 6 months (T3) after prosthesis placement. Results The 6-month survival and success rates were 100% for the short and conventional implants. Probing depths (PDs) after 6 months did not show statistical differences between short and conventional implants. All groups showed mean implant stability quotient (ISQ) values above 60 in all periods evaluated, demonstrating great implant stability, and no differences were found between groups at T3. Radiographic measurements showed an increased bone loss for conventional implants compared with short implants in all the three periods evaluated. Conclusion Our findings suggest that treatment of resorbed posterior regions in the mandible with shorter dental implants is as reliable as treatment with conventional implants after 6 months of splinted prosthesis installation. Clinical significance Short implants might be considered a predictable treatment alternative to bone augmentation or extensive surgical techniques in regions of restricted vertical bone height in the posterior region of the mandible.

In oral rehabilitation with dental implants, severely resorbed alveolar ridges are a challenging problem due to the reduced height of the residual bone. Continuous search for minimally invasive procedures has resulted in the conception of reduced-length dental implants, decreasing the necessary amount of bone for implantation, thereby reducing the need of bone-grafts. Given the growing demand in the field of implant dentistry and the continuous development of surgical techniques, this study aimed to review the current literature on the predictability and success rate of short implants. Relevant articles published in the PubMed database between the years of 2004 and 2014 were selected using the following key-words: short dental implants, extra-short implants, survival rate, implant, mandible, maxilla, prognosis, implant survival, implant length. Based on the literature review, we concluded that short implants showed high predictability and high success rate in the short term, therefore they are one of the current options for the rehabilitation of atrophic alveolar ridges. Further longitudinal studies are necessary to define more reliably parameters for their proper use, ensuring the achievement of high success rates and survival rates with the use of this type of implant.o assess the attitude and practice of dental professionals towards using of advance radiographic technique.

Background/Aim. Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses. Methods. The experiment was made in five domestic pigs. Nine weeks following domestic pigs teeth extraction, implants were placed, on the right side using surgical technique flap, and flapless on the left side. Digital dental Xrays were applied to determine primary dental implant stability quality (ISQ). At certain intervals, not later than three months, the experimental animals were sacrificed, and just before it, control X-rays were applied to measure dental implants stability. Results. Radiographic analysis showed that peri-implant bone resorption in the first 4 weeks following placement implants with flap and flapless surgical techniques was negligible. After the 3 months, mean value of peri-implant bone resorption of the implants placed using flap technique was 1.86 mm, and of those placed using flapless technique was 1.13 mm. In relation to the primary dental implant stability in the first and second week there was an expected decrease in ISQ values, but it was less expressed in the dental implants placed using the flapless technique. In the third week the ISQ values were increased in the dental implants placed by using both techniques, but the increase in flapless implant placement was higher (7.4 ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in a 4- week period, and after 3 months the dental implant stability values in the implants placed using flap technique were higher than the primary stability for 7.1 ISQ, and in the implants placed using flapless technique were higher comparing to the primary stability for 10.1 ISQ units. Conclusion. Based on the results of radiographic and resonance frequency analyses it can be concluded that the flapless technique in surgical implants placemat, leads to better results.

Narrow Diameter Implants

Abstract Background: Nowadays, narrow diameter implants are being increasingly used in posterior regions with insufficient bone width to avoid invasive bone augmentation procedures. Recent studies have indicated that narrow implants with a diameter of 3.3 to 3.5mm showed comparable survival rate with standard diameter implants. However, there are no high-quality clinical trials comparing the clinical outcomes of narrow diameter implants to standard diameter implants with augmentation procedures in atrophic posterior region. The purpose of present study is to evaluate the clinical efficacy of narrow diameter implants in posterior jaws. Methods/Design: This study is designed as a prospective, single-center, 2-arm parallel, randomized controlled clinical trial. Patients in need of single implant crowns in posterior jaws will be included in the study according to clear defined inclusion-and-exclusion criteria. Randomized number table will be used to assign the patients into two groups: group 1: narrow diameter implant group (NDI); group 2: standard diameter implant with bone augmentation group (SDI). Implant survival rate, mechanical complications, marginal bone loss, peri-implant conditions and patients’ satisfaction will be recorded. Clinical and radiological re-evaluations will be performed at 6, 12, 36, 60 months after the final crowns delivery. Discussion: Our findings will help evaluate the clinical efficacy of narrow implant in posterior region. If the results were favorable, narrow implants might be recommended as a viable alternative for posterior region with insufficient bone width.

Edentulous Patients

Aim. To evaluate the influence of primary insertion torque (IT) values of narrow dental implants on the peri-implant health, implant stability, immunoinflammatory responses, bone loss, and success and survival rates. Methods. Thirty-one edentulous patients received two narrow implants (2.9x10mm, Facility NeoPoros) to retain mandibular overdentures. The implants were categorized in four groups according to their IT: (G1) IT > 10 Ncm; (G2) IT ≥ 10Ncm and ≤ 30 Ncm; (G3) IT >30Ncm and < 45Ncm; (G4) IT ≥ 45Ncm, and all implants were loaded after 3 months of healing. The following clinical outcomes were evaluated 1, 3, 6, and 12 months after implant insertion: (i) peri-implant tissue health (PH), gingival index (GI), plaque index (PI), calculus presence (CP), probing depth (PD), and bleeding on probing (BOP); (ii) implant stability quotient (ISQ) by resonance frequency analysis; and (iii) IL-1β and TNF-α concentration in the peri-implant crevicular fluid. The marginal bone level (MBL) and changes (MBC) were evaluated. The Chi2 test, Kruskal-Wallis test, mixed-effects regression analysis, and the Kendall rank correlation coefficient were used for statistical analysis (α = 5%). Results. G1 presented the highest PD at all evaluated periods. G2 presented higher PI at month 6 and 12. G4 showed increased GI at month 3 and 12 and more CP at month 1 (p=.003). G2 and G4 had higher ISQ values over the study period, while those from G1 and G3 presented lower ISQ values. The IL-1β concentration increased until month 12 and was independent of IT and bone type; G4 had a higher IL-1β concentration in month 3 than the other groups (p=.015). The TNF-α release was negatively correlated with IT, and TNF-α release was highest in G1 at month 12. The MBL immediately after surgery and the MBC at month 12 were similar between the groups, and G4 presented a positive MBC at month 12. The survival and success rates were 75% for G1, 81.3% for G2, 64.3% for G3, and 95% for G4. Conclusion. The IT did not influence the clinical outcomes and the peri-implant immunoinflammatory responses and was weakly correlated with the narrow dental implants primary stability. The observed success rates suggest that the ideal IT for atrophic fully edentulous patients may deviate from the standardized IT of 32 Ncm.
