      guided surgical template in inexperienced surgeons: A pilot randomized controlled 
      clinical trial using resonance frequency analysis.

AB  - INTRODUCTION: There are several factors that greatly influence implant stability 
      with implant design being a paramount factor; however, few studies investigate 
      its impact. AIM: To investigate the implant stability in relation to two 
      different implant designs, a cylindrical shaped single-threaded design (CS/ST) 
      and a tapered shaped double-threaded design (TS/DT) using resonance frequency 
      analysis over the first 8 weeks after implantation. MATERIALS AND METHODS: 
      Twenty-eight implants were randomly allocated using computer-generated random 
      numbers into two groups and were placed as single tooth implant in the posterior 
      arch in human jaw as specimens. iCAT CBCT scan (Hatfield, PA) was used to 
      determine the bone density according to Misch's Bone classification. The 
      osseotomy sites were prepared and implants were placed with guided surgical 
      template by inexperienced surgeons which were prepared with the same implant 
      planning software (3shape(R) implant studio). The implant stability was measured 
      using the resonance frequency analysis Osstell(R) ISQ (Osstell AB, Sweden) on the 
      implant level over the first 8 weeks at three different time intervals. A mean 
      implant stability quotient (ISQ) value was recorded at each measurement time 
      points. The first ISQ of each implant recorded at the time of implant placement 
      were considered as baseline and were the so-called primary stability. RESULTS: 
      All 28 dental implants were analyzed. A similar pattern of implant stability 
      changes was observed in both implant designs. A significant decreased was found 
      at the first 4 weeks after implantation (p < 0.05) before ascending to maximum 
      cumulative stability by the eighth week (p < 0.05). Between the two groups, TS/DT 
      group had a higher mean ISQ values than that of the CS/ST group at all three 
      observation periods but did not reach statistical significance (p = 0.69). 
      Regarding different types of bone, TS/DT showed a significant difference in mean 
      ISQ values in D4 bone. To date, all 28 implants are in function with no 
      failure/and or complications. CONCLUSIONS: The difference in implant design did 
      not significantly influence the implant stability. TS/DT shows superiority over 
      CS/ST when placed in D4 bone and offer a significant advantage due to their 
      positive bounce back of the ISQ values by the eighth week after implant 
      installation. CLINICAL TRIAL REGISTRATION: TCTR20211020005.
