There should be no deviation between the virtually planned implantposition and the actual implant position after the implant installation regardless the technique ofconstruction of the surgical-guide. So this study was to evaluate and compare the accuracy of twodifferent CAD/CAM surgical guides in placement of all-on-4 implants. Materials and methods:A prospective randomized controlled double blind clinical study was carried out, in which twentyfour implants were placed in 6 edentulous patients. Patients were randomly allocated into one of thetwo groups: control group where surgeries were done using digital light processing (DLP) surgicalguidesand study group where implants were placed using selective laser sintering (SLS) surgicalguides.Each patient received 4 implants in the anterior part of the mandible, 2 axial implants in thecenter and 2 tilted implants at the distal ends. CBCT were taken to the implants after the surgery andthe actual implant positions were compared to the planned implant position. The deviation betweenthe planned and actual implant positions were compared between the 2 techniques of surgical guideconstructions. Results: The results of comparison between the two groups showed a statisticallysignificant difference for all comparisons, with the SLS fabricated guides showing higher deviationfrom control than those fabricated by the DLP printer.Conclusion: Although the computer manufactured surgical guides simplifies surgery and helpin optimal implant placement, there is still evidence of degree of deviation from the planned implantspositions in both of the surgical guides, particularly the SLS fabricated guides so a safety zone so asafety zone is recommended during planning to avoid to avoid critical anatomical structures.}, keywords = {All-on-four,tilted implants,implant placement,immediate loading,3D printed}, url = {https://edj.journals.ekb.eg/article_78547.html}, eprint = {https://edj.journals.ekb.eg/article_78547_d428480778ae255294323723dc6bf85b.pdf} } @article { author = {Marei, Hesham}, title = {The use of computer-guided surgery via a partially guided protocol does not completely compensate for the level of operator experience in implant placement}, journal = {Egyptian Dental Journal}, volume = {64}, number = {Issue 4 - October (Oral Surgery)}, pages = {3257-3265}, year = {2018}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2018.78550}, abstract = {Purpose: There is always a tension between allowing novice trainees to place implantsindependently and the need to achieve accurate functional and esthetic outcomes. We aimed tomeasure the influence of surgeon experience on the accuracy of implants placed using a teethsupportedsurgical guide via a partially guided surgical protocol in a clinical setting.Materials and Methods: Twenty partially edentulous patients were randomly allocatedto expert and novice surgeon groups. Implant drilling and placement for the two groups wereperformed through a flapless surgical technique using surgical guides following a partially guidedsurgical protocol. The study primary independent variable was the surgeon experience, whilethe outcome variable was the accuracy, which was measured based on the differences in implantangulations pre- and postoperatively. Two-way analysis of variance (ANOVA) was applied to findthe influence of surgeon experience, implant size, and the interactive effect of surgeon experienceand implant size on the angular deviation.Results: A total of 40 implants were inserted in 7 males and 13 females. There was no significantdifference (p = 0.453) in the mesio-distal deviation between the expert and novice groups. In abucco-lingual direction, the expert group performed more accurate implant placement (3.7 ± 3.35)compared with the novice surgeons (8.5 ± 6.3). There was no effect for implant size and/or theinteraction effect on the degree of angular deviations.Conclusion: The level of surgeon experience affects the accuracy of implants placed using ateeth-supported surgical guide in a bucco-lingual direction; therefore, the use of computer-guidedsurgery via a partially guided protocol does not completely compensate for the level of operatorexperience. However, such surgical guide might be used in a whole task training of novice surgeons,as it can bridge a gap between simulation training in vitro and free-hand surgery in a clinical setting.}, keywords = {}, url = {https://edj.journals.ekb.eg/article_78550.html}, eprint = {https://edj.journals.ekb.eg/article_78550_91eba042d50750be5154113c00e9de15.pdf} } @article { author = {Amr, Khaled and Kamel, Heba and Hatem, Hussein}, title = {Computer manufactured Patient-specific Auto-reducible plate versus standard Trapezoid plate in Unilateral Subcondylar fractures}, journal = {Egyptian Dental Journal}, volume = {64}, number = {Issue 4 - October (Oral Surgery)}, pages = {3267-3276}, year = {2018}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2018.78552}, abstract = {Purpose: Subcondylar fractures account for a high incidence of mandibular fracturesrepresenting a frustrating clinical dysfunction and serious complications when maltreated. Thisstudy aimed to compare the computer designed and manufactured patient-specific auto-reducibleplate to the standard trapezoid plate in attempt to reach the optimal geometrical design forsubcondylar fracture plate fixation.Patients and methods: A total of sixteen patients suffering from unilateral subcondylar fracturewere included in this study from the outpatient clinic of the department of oral and maxillofacialsurgery, faculty of Dentistry, Cairo University. All patients were subjected to preoperative clinicalevaluation and 3-D CT examination to assess the degree of fracture displacement and condylarlocation. The selected patients were divided into two groups, eight patients each. In group A patients,virtual fracture reduction through mirroring of the unaffected intact side was performed, which wasthen used as a template for designing and processing of the titanium patient-specific condylar platevia direct metal laser sintering. While in group B patients, the unilateral sub-condylar fractures weremanually reduced into position and fixed in place by the standard trapezoidal mini-plate. Fixationof the plates in both groups was then performed using 2.0 mini-screws. Postoperative clinicalassessment of the occlusion, Maximum inter-incisal opening (MIO) and mandibular deviation wasdone at one week, 1 month & 3 months. Immediate postoperative radiographic assessment wasperformed through the superimposition of the postoperative CT data of the fixed fracture on thepreoperative virtually reduced mandibular model as a reference CT data to validate and comparethe accuracy of the achieved postoperative fixation in both groups.Results: The surgeries in all cases proceeded without any complications. Surgical siteexamination was normal with no signs of infection. The occlusion was satisfactory at the end of thestudy interval despite the initial slight immediate postoperative occlusal discrepancy found in bothgroups. Deviation was not completely absent in both groups at the end of the follow-up period. TheMIO ranged from 39-47 mm at the end of the study with no significant difference between bothgroups. The CT scan revealed the almost precise adaptation of both plates in place with no significantdifference, however, with the advantageous fracture auto-reduction, intra-operative time saving andease of application recorded with the use of the PS-condylar plate in group A patients. The meanoperating time for reduction and fixation using the PS-condylar plate was 90 minutes comparedto a mean of 88 minutes using the standard reduction and trapezoid plate fixation technique.Conclusion: Despite of the approaching accuracy of both plates, preoperative digital virtualplanning and PS-plate processing were highly beneficial in the auto-reduction of the fracturedsegments. The intra-operative time saving and ease of application with less obtained surgical errorsdue to the planned surgery and the perfect fit of the prosthesis were found very valuable. Therefore,accommodating with the continuous technological updates, the integration of computer programsin surgery planning and plate designing and manufacturing in subcondylar fractures is highlydesirable due to its great benefits.  }, keywords = {Subcondylar fracture,Computer-manufactured plate,auto-reducible}, url = {https://edj.journals.ekb.eg/article_78552.html}, eprint = {https://edj.journals.ekb.eg/article_78552_e1d759d0dce58bee9ce6931adfa2e74e.pdf} }
