    Abstract: Effects of length and location of the edentulous area on the accuracy of prosthetic treatment plan incorporation into cone‐beam computed tomography (CBCT) scans has not been investigated. Purpose To evaluate the effect of length and location of the edentulous area on the accuracy of prosthetic treatment plan incorporation into CBCT scans using different methods. Material and Methods Direct digital scans of a completely dentate master model with removable radiopaque teeth were made using an intraoral scanner, and digital scans of stone duplicates of the master model were made using a laboratory scanner. Specific teeth were removed to simulate different clinical situations and their CBCT scans were made. Surface scans were registered onto the CBCT scans. Radiographic templates for each clinical situation were also fabricated and used during CBCT scans of the master models. Using metrology software, three‐dimensional (3D) deviation was measured on standard tesselation language (STL) files created from the CBCT scans against an STL file of the master model created from a CBCT scan. Statistical analysis was done using the MIXED procedure in a statistical software and Tukey HSD test (α =.05). Results The interaction between location and method was significant ( P  = .009). Location had no significant effect on registration methods ( P   〉  .05), but on the radiographic templates ( P  = .011). Length of the edentulous area did not have any significant effect ( P   〉  .05). Conclusions Accuracy of digital image registration methods was similar and higher than that of radiographic templates in all clinical situations. Tooth‐bound radiographic templates were significantly more accurate than the free‐end templates. The results of this study suggest using image registration instead of radiographic templates when planning dental implants, particularly in free‐end situations.

    In: Journal of Clinical Periodontology, Wiley, Vol. 39, No. 2 ( 2012-02), p. 188-195
    Abstract: The aim of the present study was to evaluate an early loading protocol for surface modified implants placed in the posterior mandible. Material and Methods:  A total of 134 implants with a TiO 2 blasted, fluoride modified surface were inserted into the posterior mandibles of 44 patients. The implants were functionally loaded after 7 weeks of healing. Implant stability quotient ( ISQ ) values (during the first year), bleeding on probing ( BOP ), plaque accumulation and marginal bone level ( MBL ) were assessed until the end of the observation period of 5 years. A total of 41 patients with 123 implants completed the study. Results:  No implants were lost. ISQ values decreased significantly from the time of insertion to 2 weeks and increased significantly until the 1‐year follow up. BOP varied until the end of the observation period between 7.9% and 13.0%. Plaque accumulation decreased from the time of early loading to the end of the study. MBL changed from 0.59 mm at the time of implant placement to 0.80 mm at the time of early loading. Thereafter, only slight variations in MBL occurred until the end of the observation period. Conclusions:  The results confirm that early loading is a promising option also in posterior edentulism of the mandible.

    Reliability of Implant Placement With Stereolithographic Surgical Guides Generated From Computed Tomography: Clinical Data From 94 Implants
    Wiley ; 2008
    In:  Journal of Periodontology Vol. 79, No. 8 ( 2008-08), p. 1339-1345
    Details
    In: Journal of Periodontology, Wiley, Vol. 79, No. 8 ( 2008-08), p. 1339-1345
    Abstract: Background: Dental implant placement requires precise planning with regard to anatomic limitations and restorative goals. The aim of this study was to evaluate the match between the positions and axes of the planned and placed implants using stereolithographic (SLA) surgical guides. Methods: Ninety‐four implants were placed using SLA surgical guides generated from computed tomography (CT) between 2005 and 2006. Radiographic templates were used for all subjects during CT imaging. After obtaining three‐dimensional CT images, each implant was virtually placed on the CT images. SLA surgical guides, fabricated using an SLA machine with a laser beam to polymerize the liquid photo‐polymerized resin, were used during implant placement. A new CT scan was taken for each subject following implant placement. Special software was used to fuse the images of the planned and placed implants, and the locations and axes were compared. Results: Compared to the planned implants, the placed implants showed angular deviation of 4.9° ± 2.36°, whereas the mean linear deviation was 1.22 ± 0.85 mm at the implant neck and 1.51 ± 1 mm at the implant apex. Compared to the implant planning, the angular deviation and linear deviation at the neck and apex of the placed maxillary implants were 5.31° ± 0.36°, 1.04 ± 0.56 mm, and 1.57 ± 0.97 mm, respectively, whereas corresponding figures for placed mandibular implants were 4.44° ± 0.31°, 1.42 ± 1.05 mm, and 1.44 ± 1.03 mm, respectively. Conclusion: SLA surgical guides using CT data may be reliable in implant placement and make flapless implant placement possible.

    Abstract: The purpose of this retrospective study was to report the implant and prosthetic complications of mandibular metal‐resin fixed complete dentures (MRFCDs) opposing a maxillary complete removable dental prosthesis (CRDP) in a 15‐ to 20‐year post‐placement follow‐up period. Material and methods Dental records of 24 edentulous patients treated by a mandibular MRFCD and a maxillary CRDP were reviewed. Complications for the implants, MRFCDs, and CRDPs were recorded in four different recall periods: 0–5 years, 5–10 years, 10–15 years, and more than 15 years. The survival and failure times based on Kaplan–Meier statistics were analyzed using Lifetest procedures. Product‐limit survival estimates were used for cumulative survival rates (CSRs). Results The mean service time was 18.5 years. The CSR for the implants and MRFCDs was 91.8% at 16.9 years (confidence intervals: 85.2% and 95.5%) and 80% at 19.6 years (confidence intervals: 44.1% and 94.1%), respectively. The implant failures after 15 years occurred because of a tumor resection. Acrylic resin tooth fracture (45.8% of patients) and wear (75% of patients) were the most common complications with the MRFCD. Retaining screw complications [loosening (8.1% of retaining screws) and fracture (11.3% of retaining screws)] were also common. Conclusions The outcomes seen with MRFCD over the long term were favorable. After placement of prostheses, 1 implant loss was observed potentially due to prosthetic/hygiene/periodontal factors. However, potential maintenance complications such as acrylic resin tooth fracture and/or wear and retaining screw loosening and fracture may occur in the long term when a similar design is used for the mandible.

    Abstract: Microleakage through the interface has been documented in implant systems with titanium ( T i) abutments. There is a current increase in the use of zirconia ( Z i) abutments especially in esthetic zone in where higher risk of visible metal color through the peri‐implant tissues exists. Purpose The aim of the present in vitro study is to evaluate the leakage at the implant fixture–abutment interface with two different screw‐retained abutment systems at different torque values in a nonloading condition. Materials and Methods In vitro study design included four groups ( T i and Z i torqued at 25 and 15 Ncm [ N  = 8/group]). Microcomputed tomography (micro‐ CT ) was chosen to detect microgap. Microleakage from the implant chamber to the external milieu was evaluated using limulus amebocyte lysate ( LAL ) test, while microleakage from external milieu to the implant chamber was evaluated using toluidine blue dye ( TBD ) and colorimeter. Results Micro‐ CT images did not reveal any microgap. LAL test showed that there is a time‐, abutment‐, and torque‐dependent increase in microleakage ( p  = .001) with Z i torqued at 15 Ncm having higher leakage with time compared with T i torqued at 15 Ncm ( p  = .002), as well as Z i torqued at 15 Ncm having higher leakage with time compared with Z i torqued at 25 Ncm ( p  = .01). TBD test showed a nonsignificant increase in microleakage with higher leakage related to titanium abutment groups ( p   〉  .05). Repeated torque/antitorque handling differentially affected microleakage ( p  = .01). Conclusions Within the limits of this study, there is a statistically significant difference in bidirectional microleakage with time, abutment type, and torque values being major players for leakage from internal implant chamber to external milieu, while the abutment type and time but not the torque value being important factors for leakage from external milieu into implant chamber in nonloading condition. Future studies are needed to determine peri‐implant health around Zi abutments.

    Abstract: Background: The quality of bone is an important factor in the successful implant treatment, and it is evident that higher implant failure is more likely in poor quality of bone. The primary stability of oral implants related to resistance to micromotion during healing is influenced by bone quality, surgical technique, and implant design. Purposes: The aims of this biomechanical study were to explore the effect of bone quality on initial intraosseous stability of implants, and to determine the correlations between the bone quality and implant stability parameters. Materials and Methods: Twenty‐four implants (Neoss Ltd., Mölnlycke, Sweden) were placed into anterior and posterior regions of three human cadaver mandibles. The bone densities of implant recipient sites were preoperatively determined using computerized tomography (CT) in Hounsfield unit (HU). The maximum insertion torque values were recorded, and primary implant stability measurements were noninvasively performed by means of resonance frequency analysis (RFA). Results: The bone density values ranged from −267 HU to 553 HU. It was found that mean bone density, insertion torque, and RFA values were 113 ± 270 HU, 41.9 ± 5 Ncm, and 70 ± 7 implant stability quotient (ISQ), respectively. Statistically significant correlations were found between bone density and insertion torque values ( r  = 0.690, p   〈  .001); bone density and ISQ values ( r  = 0.557, p   〈  .05); and insertion torque and ISQ values ( r  = 0.853, p   〈  .001). Conclusion: CT is a useful tool to assess bone quantity and quality in implant recipient sites, and bone density has a prevailing effect on implant stability at placement.
