“…Several other clinical studies have investigated the clinical performance of implants with diameters between 3 mm and 3.5 mm supporting fixed partial dentures (FPDs), with survival rates from 93.8% to 100%. (7,8,11,(13)(14)(15)(16)(17)(18) Only a few studies have considered immediate provisionalization of NDIs, mainly in the anterior maxilla. (10,11) …”

Narrow-diameter implants (NDIs) are increasingly produced and used in implant dentistry, especially since the introduction of new, more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤6 mm were treated with 1 or several NDIs. The surgical protocol was chosen according to the clinical situation: (1) flapless, (2) mini-cervical flap, (3) wide flap, (4) wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates, and patient-centered outcomes were evaluated after a follow-up period of 1 year. A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All but 1 implant reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7%. The need for GBR was avoided in 60% of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was −0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition. In conclusion, use of NDIs to restore partial edentation in sites with limited horizontal thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results.

Effect of Different Types of Luting Cements on Retention and Marginal Adaptation of Implant-Supported Crowns (An in Vitro Study)

Aim:The purpose of this study was to evaluate the retention values and marginal adaptation of implant-supported metal copings using different luting agents. Material and Method:Forty implant fixtures and solid abutments of 7mm height were embedded vertically in epoxy resin blocks. Metal copings with a loop on the occlusal surface were fabricated using base metal alloy. The copings were luted using four different cements (Multilink N, Fuji Plus, Fuji1 and Adhesor) under static load of 5kg (n=10). All specimens were subjected to 1000 thermal cycles between 5˚c and 55˚c with a dwell time of 10 seconds in a thermocycling device. Marginal accuracy was detected before and after cementation of all specimens by stereomicroscope. TheTensile force required to dislodge the copings were determined by a computer controlled universal testing machine with a cross-head speed of 0.5 mm/ min.The force in Newton(N) required to remove the copings was recorded. Data was collected and statistically analyzed.Results: Multilink N and Fuji1 had the highest and the least mean retentive strength respectively. There was no significant difference between MultilinkN, Fuji Plus and Adhesor. The absolute marginal discrepancies of cements were in reducing order zinc phosphate , resin modified glass ionomer, glass ionomer and resin cement.Conclusion: within the conditions of this study, resin cement, the resin modified glass ionomer and zinc phosphate had statistically the same retentive quality and are recommended for definitive cementation of single implant-supported restoration. Different luting media had a definite effect over the final fit of all metal copings, but they were all within the clinically accepted level of 100 µm.

“…Conversely, results from previous studies on narrow-diameter implants indicate a survival rate of between 96% and 99.4% with follow-ups of 1-5 years and irrespective of the surgical approach used (two-stage surgical approach, one-stage surgical approach, or immediate-function approach; 6,[15][16][17]. However, the limited sample size (12,17) and follow-up duration (12,15) of these studies may increase potential bias, obscuring the true outcomes of fixedprosthetic rehabilitations supported by narrow-diameter or short-length implants.…”

Abstract:We investigated the short-term clinical outcomes of narrow-diameter short-length implants for the fixed-prosthetic partial rehabilitation of extremely resorbed jaws. Twenty-three patients requiring partial rehabilitations with narrowplatform short-length implants in any jaw were included in this study. In total, 30 implants 3.3 mm in diameter and 7 (n = 15 implants) or 8.5 (n = 15 implants) mm in length were inserted. The primary outcome measure was implant cumulative survival rate (CSR); the secondary outcome measures were marginal bone resorption at 1 and 3 years and the incidence of biologic and mechanical complications. Five patients (21.7%) with six implants (20%) were lost to follow-up. Two implants failed in two patients, yielding a CSR at 3 years of follow-up of 93.4%. The average (standard deviation) marginal bone resorption was 1.34 mm (0.95 mm) after the first year and 1.38 mm (0.78 mm) after the third year. Biologic complications occurred in three patients; mechanical complications occurred in three patients. Despite the limitations of the study, our findings show that the use of new narrow-diameter short-length implants for the rehabilitation of extremely atrophic regions is viable in the short-term, and can be considered a treatment alternative in extremely resorbed jaws.
