Clinical Trial Summary

The objectives of this clinical study were to assess the effect of different ITs and bone types on POP levels and survival rates and to investigate the effect of different patient- and site-related factors on POP levels and survival rates.

Description:

This prospective clinical study included 230 patients treated with a single tapered screw implant (Bioinnovation Dental®, Brazil). The implants were placed using the appropriate burs with a final master drill of 3.5 or 4.5 mm in diameter by one senior oral surgeon. These implants were multi-threaded, and their surfaces were both sandblasted and acid etched. Of the 230 participants, 172 received a single 5 x 10-mm implant, and 58 received a 4 x 10-mm implant. For the higher torque range (90 - 200 Ncm), the maximum IT was recorded with an electronic digital torque measuring device (Tohnichi BTGE200CN-G, Hitachi, Japan), while a different gauge (Tohnichi BTG90CN-S, Hitachi, Japan) was used for the lower torque range (10 - 90 Ncm). All implants were placed at the crestal level and closed with a cover screw, and the flap was then sutured with non-resorbable 4/0 nylon suture (Resorba® Germany). Pain levels were recorded at day 1, 2 and 4 and at week 1, 2 and 3 after surgery using visual analog scale (VAS) ranging from 0 "no pain" to 10 "worst pain ever. Implants were classified into 4 groups based on the IT value; Low: 60 implants (10-29 Ncm, mean=15 Ncm); Regular: 102 implants (30-50 Ncm, mean=42 Ncm); High: 47 implants (51-100 Ncm, mean=75 Ncm); and Very high: 21 implants (101-200 Ncm, mean=170 Ncm). Implant survival was assessed clinically and radiographically at 3, 6, 12, 24 and 36 months. The criteria for implant success according to Buser et al, were no radiolucent zone around the implant, confirmed individual implant stability, and no suppuration, pain or ongoing pathologic processes. All implants that failed to fulfill these success criteria were regarded as failures. The effect of IT, bone type, implant location, age, gender and smoking was measured with regression analysis. Kaplan-Meier survival analysis was performed to calculate the overall implant survival probabilities. The level of statistical significance was set at p<0.05.

Intervention

Procedure:
• Implant insertion
All patients received a single Tapered Screw implant (Bioinnovation Dental®, Brazil). The implants were placed according to the manufacturer's instructions by using the appropriate burs with a final master drill of 3.5 or 4.5 mm in diameter by one senior oral surgeon. These implants were multi-threaded, and their surfaces were both sandblasted and acid etched. Of the 230 participants, 172 received a single 5 x 10-mm implant, and 58 received a 4 x 10-mm implant.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Post-operative pain	Pain was assessed after surgery using the 10-cm visual analog scale (VAS) ranging from 0 "no pain" to 10 "worst pain ever." The scale has no other markings along the line. Patients will be asked to record their pain level before surgery and after surgery, 24 hours after surgery, at day 2, day 4 and at week 1, week 2, and week 3.	1 month
Secondary	Survival rate of implants	Implant survival was assessed clinically and radiographically at 3, 6, 12, 24 and 36 months. The criteria for implant success according to Buser et al, were no radiolucent zone around the implant, confirmed individual implant stability, and no suppuration, pain or ongoing pathologic processes (Buser et al., 1997). All implants that failed to fulfill these criteria were regarded as failures.	36 months
