RESUMO

The purpose of this clinical research was to evaluate peri-implant marginal changes around immediate implants placed either with the application of SCTG or XCM or without soft tissue grafting. A total of 48 patients requiring a single implant-supported restoration in the anterior jaw were selected for inclusion. Three surgical procedures were performed, as follows: type 1 implant with subepithelial connective tissue graft (SCTG), type 1 implant with xenogenic collagen matrix (XCM), and type 1 implant without soft tissue augmentation (NG) (control group). The marginal change of peri-implant soft tissue, facial soft tissue thickness (FSTT), peri-implant health status, esthetics, and patient satisfaction were assessed at one year after surgery. All of the placed implants showed a survival rate of 100%. No significant differences in FSTT were recorded between the SCTG group and the XCM group after treatment (P > 0.05), while the NG group presented a significant difference (P < 0.05). Patients in the NG group lost significantly more in the buccal marginal level than did patients in the SCTG group and those in the XCM group (P < 0.05). The favourable success rate recorded in all groups confirmed immediate tooth replacement as a choice of treatment for a missing anterior single tooth. The NG group presented significant changes of FSTT and buccal marginal level, while XCM constituted a viable alternative to SCTG.

RESUMO

Minimally traumatic tooth removal is the norm for removing teeth when a dental implant is planned at that site. The quantity of available bone is the primary requisite to place an implant. The initial use of a scalpel blade to widen the periodontal space followed by the use of luxators is one of the techniques that is being followed for atraumatic extraction. A case of accidental breakage of a number 11 scalpel blade while attempting tooth removal and the method adopted in removing this portion of the blade without further bone destruction is reported here. The authors have not found any previously published cases, reporting the breakage of a scalpel blade during the bone expansion procedure and its management.

RESUMO

Objectives: With regard to the prevalence of abutment screw loosening (SL) and bone height reduction, particularly in the posterior regions of the jaws, as well as the contradictory issue of applying short implants instead of surgeries, along with all preparations associated with longer implants, the present study aimed to compare the amount of torque loss in short implants with increased vertical cantilever abutments and standard ones. Material and Methods: In this experimental study, a total number of 20 implants (MegaGen Implant Co., Ltd, South Korea) with 4.5 mm diameter including 10 short implants (7 mm) and 10 standard ones (10 mm) were utilized. Using a surveyor, fixtures were perpendicularly mounted in 13×34 mm resin for short implants and 19×34 mm resin for standard ones. The abutments of the same height but different cuff heights (2.5 mm for the standard implants and 5.5 mm for the short ones) were then tightened with 30 N.cm, via a digital torque meter. To compensate the settling effect, the abutment screw was re-tightened with 30 N.cm after 10 min. Upon applying 500,000 cycles at 75 N.cm and 1 Hz along the longitudinal axis on each sample, blind reverse torque value (RTV) was measured with a digital torque meter. The data were finally analyzed using Student's t-test. Results:Both groups experienced torque loss, but there was no statistically significant difference between the case and control groups in terms of abutment SL (p = 0451). Conclusion: Short implants seem to be a good mechanical alternative in emergencies with respect to torque loss and abutment SL. (AU)


Objetivos: Considerando a prevalência de afrouxamento de parafuso dos pilares, redução da altura óssea especialmente nas regiões posteriores, a questão contraditória da aplicação de implantes curtos em vez de cirurgias e todos os preparos associados a implantes mais longos, este estudo buscou comparar implantes curtos com pilares cantilever verticais aumentados e implantes padrão na quantidade de perda de torque. Material e métodos: Neste estudo experimental, foram utilizados 20 implantes (Megagen, Coreia do Sul) com diâmetro de 4,5 mm, incluindo 10 implantes curtos (7 mm) e 10 implantes padrão (10 mm). A fixação foi realizada perpendicularmente em uma resina 13 × 34 mm para implantes curtos e uma resina 19 × 34 mm para implantes padrão, usando um topógrafo. Os pilares da mesma altura, mas com diferentes comprimentos de manguito (2,5 mm para os implantes padrão e 5,5 mm para os implantes curtos) foram apertados com 30 N, utilizando um torquímetro digital. Para compensar o efeito de sedimentação, o parafuso do pilar foi reapertado com 30 N após 10 min. Depois de aplicar 500.000 ciclos a 75 N e 1 Hz ao longo do eixo longitudinal em cada amostra, o valor de torque reverso cego foi medido com um medidor de torque digital. Os dados foram analisados pelo teste t de Student. Resultados: Todos os grupos tiveram perda de torque, mas não houve diferença estatisticamente significativa entre os grupos caso e controle em termos de afrouxamento do parafuso do pilar (p = 0451). Conclusão: Os implantes curtos parecem ser uma boa alternativa mecânica em emergências em termos de perda de torque e afrouxamento do parafuso do pilar. (AU)

RESUMO

Objetivo: Avaliar a relação entre a densidade óssea medida em imagens de tomografia computadorizada (TC) e tomografia computadorizada de feixe cônico (TCFC) e relacionar com a estabilidade primária de implantes dentários. Material e métodos: Foram utilizadas neste estudo 20 cabeças femorais bovinas frescas, preparadas pela remoção de partes moles, secção do osso e colocação de marcadores para localização e angulação dos implantes. A densidade óssea da área peri-implantar foi determinada no pré-operatório em imagens TC e TCFC das amostras de osso peparado, representadas por unidades Hounsfield (HUs) e valores de cinza (GVs), respectivamente. Em seguida, 60 implantes em três tamanhos (diâmetro = 4 mm, comprimento = 8, 10 e 12 mm) foram inseridos nos ossos e o torque máximo de inserção (TI) foi registrado. O dispositivo Osstell também foi usado para determinar o quociente de estabilidade do implante (ISQ) para cada implante. A análise estatística foi realizada nos dados (α = 0,05). Resultados: Os valores médios ± DP de GV,HU e ISQ foram 1592,75 ± 231,82, 675,26 ± 115,38 e 61,90 ± 10,14, respectivamente. Além disso, o limite de TI mais frequente foi 30-35 Ncm (41,4%). Relações significativas foram observadas entre HU e IT, GV e IT, HU e ISQ, GV e ISQ, e IT e ISQ em todos os tamanhos de implante. Os GV e HU também se correlacionaram significativamente. Conclusão: Os valores da densidade óssea em imagens de TCFC e TC mostram-se positivamente associados para estabilidade primária de implantes dentários. Portanto, os GVs obtidos no Sistema de TCFC (Sirona's Galileos) poderiam ser usados para a seleção pré-operatória de sítios edêntulos que permitam uma melhor estabilidade do implante ou locais que requerem procedimentos adicionais para aumentar a taxa de sucesso dos implantes dentários. (AU)


Objective: To evaluate the relationship between bone density measured by computed tomography (CT) and cone beam computed tomography (CBCT) (Sirona's Galileos scanner) with primary stability of dental implants. Material and methods: 20 fresh bovine femoral heads were prepared by removal of soft tissue, sectioning of the bone, and placement of markers for location and angulation of implants. Bone density of peri-implant areas was determined preoperatively by CT and CBCT scanning of the prepared bone samples represented by Hounsfield units (HUs) and gray values (GVs), respectively. Then, 60 implants in three sizes (diameter = 4 mm, length = 8, 10, and 12 mm) were inserted into the bones and maximum insertion torque (IT) was recorded. Osstell device was also used for determining the implant stability quotient (ISQ) for each implant. Statistical analysis was performed on the data (α = 0.05). Results: Mean ± SD values of GV,HU, and ISQ were 1592.75 ± 231.82, 675.26 ± 115.38 and 61.90 ± 10.14, respectively. Moreover, the most frequent IT limit was 30-35 Ncm (41.4%). Significant relationships were observed between HU and IT, GV and IT, HU and ISQ, GV and ISQ, and IT and ISQ in all implant sizes. Moreover, GV and HU also significantly correlated to each other. Conclusion: Bone density values in CBCT and CT scans are positively associated to primary stability of dental implants. Therefore, GVs obtained from Galileos CBCT scanner can be used for preoperative selection of edentulous sites which allow for better implant stability or locations which require further procedures for enhancing the success rate of dental implants (AU)

RESUMO

ABSTRACT Introduction: The passivity of prosthetic components is one of the most important prerequisites in oral implant rehabilitation for maintenance of osseointegration. Objective: Thus, the present study analyzed in vitro the accuracy of different molding techniques in prosthetic rehabilitation on angled implants installed in an anatomical model of a metallic edentulous maxilla. Methods: Laboratory experiment study. A reference metal model of an edentulous maxilla was used. A metal framework was used for the misadaptation assessment. Three groups (n= 10) were compared and impressions were made with vinyl-polysiloxane and casts were obtained with type IV stone: (1) Impression with a metallic open-tray without splinted transfers; (2) Impression with a metallic open-tray and metal splinted transfers; (3) Impression with a multifunctional guide and metal splinted transfers. Misadaptation was assessed with the aid of a stereomicroscope and measuring software. Data were submitted to ANOVA with Welch correction and the Games-Howell post-hoc test with the significance set at 5 percent. Results: Misadaptation (µm) was 110,23 ± 30,94, 37,53 ± 3,92, and 37,69 ± 2,79 for the the groups. Statistically significant differences between impression with a metallic open-tray with and without splinted transfers were observed (p < 0,001). No significant differences between the other types of impression. Conclusions: Impression with a metallic open-tray without splinted transfers and with a multifunctional guide splinted with metal transfers were the most precise methods resulting in higher accuracy in transferred implants(AU)

RESUMO

The results of a comparative assessment of the state of hemomicrocirculation and oxygen metabolism in the mucous membrane of the alveolar crest after contour plastics of the gums during dental implantation using a connective tissue graft from the upper jaw, a connective tissue transplant from the palate and the collagen matrix collagen matrix are presented. During contouring with the use of connective tissue graft (CTG) from the upper jaw and collagen matrix in the mucous membrane of the alveolar mandible, the level of tissue blood flow decreases, which characterizes the development of ischemia, which is stopped after 3 weeks, when using a connective tissue graft (CTG) from the palatine, the level of tissue blood flow rises, which indicates the development of hyperemia, which is stopped for more than 3 weeks. According to oximetry data after contouring with the use of various surgical techniques, the level of oxygenation and oxygen metabolism is reduced by 8-38%, which characterizes the development of hypoxia, which is stopped after 3 weeks when using CTG from the hillock of the upper jaw and collagen matrix for more than 3 weeks when applying CTG from the palatine.

RESUMO

RESUMEN La estomatitis subprótesis es una de las lesiones más frecuentes encontradas en la consulta de Estomatología. Es una enfermedad comúnmente asintomática, cuya génesis es multifactorial, y tiene una alta prevalencia en pacientes portadores de prótesis removibles. Predecir su aparición resultaría muy oportuno pues permitiría alcanzar beneficios económicos y para la salud del individuo. Por ello, es importante desarrollar un modelo predictivo del riesgo a padecer estomatitis subprótesis. Se realizó este estudio en los pacientes que acudieron a la consulta de prótesis de la Clínica Estomatológica «Victoria de Santa Clara¼. Dicha investigación se caracterizó por la obtención de un modelo predictivo de la enfermedad. Los principales factores predictivos de la enfermedad fueron: la higiene bucal deficiente y la mala calidad de las prótesis. Se confeccionó una ecuación logística y se obtuvo un modelo predictivo con el propósito de conocer los pacientes con más probabilidades de padecer dicha enfermedad.


ABSTRACT Subprosthesis stomatitis is one of the most frequent lesions found in a dental consultation. It is a commonly asymptomatic disease, whose origin is multifactorial, and has a high prevalence in patients with removable prostheses. Predicting its appearance would be very timely as it would allow reaching economic benefits and benefits for individual's health. Therefore, it is important to develop a predictive model of the risk of suffering from subprosthesis stomatitis. This study was carried out on patients who came to the prosthesis consultation at "Victoria de Santa Clara" Dental Clinic. It was characterized by the elaboration of a predictive model of the disease. Poor oral hygiene and poor quality of the prosthesis were the main predictive factors of the disease. A logistic equation was made and a predictive model was obtained in order to know the patients with more probabilities of suffering from this disease.

RESUMO

BACKGROUND: To assess the effect of implantoplasty and implant-abutment design on the fracture resistance and macroscopic morphology of narrow-diameter (3.5 mm) dental implants. MATERIAL AND METHODS: SCREW-shaped titanium dental implants (n = 48) were studied in vitro. Three groups (n = 16) were established, based on implant-abutment connection type: external hexagon, internal hexagon and conical. Eight implants from each group were subjected to an implantoplasty procedure; the remaining 8 implants served as controls. Implant wall thickness was recorded. All samples were subjected to a static strength test. RESULTS: The mean wall thickness reductions varied between 106.46 and 153.75 μm. The mean fracture strengths for the control and test groups were, respectively, 1211.90 ± 89.95 N and 873.11 ± 92.37 N in the external hexagon implants; 918.41 ± 97.19 N and 661.29 ± 58.03 N in the internal hexagon implants; and 1058.67 ± 114.05 N and 747.32 ± 90.05 N in the conical connection implants. Implant wall thickness and fracture resistance (P < 0.001) showed a positive correlation. Fracture strength was influenced by both implantoplasty (P < 0.001) and connection type (P < 0.001). CONCLUSIONS: Implantoplasty in diameter-reduced implants decreases implant wall thickness and fracture resistance, and varies depending on the implant-abutment connection. Internal hexagon and conical connection implants seem to be more prone to fracture after implantoplasty

RESUMO

OBJETIVO: El objetivo de este artículo es describir la rehabilitación sobre implantes en un caso de alta demanda estética, basando dicho tratamiento en una planificación íntegramente digital. CASO CLÍNICO: Se presenta el caso clínico de una paciente de 52 años de edad que acude por fractura del diente 2.1. Tras el diagnóstico y análisis, tanto de forma clínica como radiográfica, se determina un pronóstico restaurador imposible para el 2.1, planificando como tratamiento una rehabilitación implantosoportada. Se realizó un escaneado de la zona a tratar para llevar a cabo un estudio detallado del caso y la confección de una corona provisional, la cual se atornilló en el mismo momento de la cirugía a un implante colocado de forma inmediata postextracción. Sumado a ello, se realizaron injertos de tejido duro y blando para asegurar el mantenimiento de los contornos periimplantarios. Tras el periodo de integración del implan-te, se trabajó el contorno de la corona provisional hasta conseguir un perfil de emergencia y un volumen de tejido gingival idóneos. Tanto el perfil de emergencia conseguido como el contorno del provisional fueron escaneados, junto con la posición del implante, para la confección de la restauración metal-cerámica definitiva. A los 6 meses tras la finalización del caso, se observa una estética de tejidos blandos idónea y un mantenimiento perfecto de toda la arquitectura gingival. CONCLUSIÓN: El manejo del sector estético anterosuperior evidencia una clara exigencia estética. En casos de pérdida dentaria en esta localización, la rehabilitación fija sobre implantes es el tratamiento de elección. No obstante, para conseguir un resultado adecuado y predecible, es esencial un correcto manejo quirúrgico y protésico. La planificación mediante medios digitales supone un salto de calidad en el enfoque terapéutico de estos casos, permitiendo un tratamiento más exacto e individualizado y siendo, además, más sencilla y eficiente la información que se traslada al laboratorio protésico


AIM: The purpose of this article is to present a clinical case of high aesthetic demand. Such planning and treat with digital flow, included diagnosis, prosthetic planning and finally, the placement of the final prosthesis. CASE REPORT: A 52-year-old woman presents a fracture of the tooth 2.1. After diagnosis and analysis both clinically and radiographically, an impossible restorative prognosis is determined for 2.1, planning implant-supported rehabilitation as treatment. A scan of the area to be treated was carried out to carry out a detailed study of the case and the preparation of a provisional crown, which was screwed at the same time of surgery to an implant placed immediately post-extraction. Besides, hard and soft tissue graft were placed to guarantee the maintenance of the peri-implant contours. After the implant osteointegration, the contour of the provisional crown was scanned to obtain a suitable emergence profile and gingival tissue volume. Both the emergency profile obtained and the contour of the provisional were scanned together with the position of the implant for the preparation of the final metal-ceramic restoration. After six months, it can observe an ideal soft tissue aesthetic and perfect maintenance of the entire gingival architecture. CONCLUSION: The management of the anterior superior aesthetic sector shows a clear aesthetic demand. In cases of tooth loss at this location, fixed implant rehabilitation is the treatment of choice. However, to achieve an adequate and predictable result, proper surgical and prosthetic management is essential. Digital flow it present like alternative and a quality leap in the therapeutic approach to these cases, a more accurate and individualized treatment, and the information that is transferred to the prosthetic laboratory is more simple and efficient

RESUMO

BACKGROUND: The aim of this case report was to use a surgical technique for autotransplantation of tooth using virtually planned 3D printed surgical templates for guided osteotomy preparation of the recipient of donor tooth. CASE PRESENTATION: An 18-year-old male patient received autotransplantation of the right mandibular third molar to replace an included right second molar. This procedure was based on guided implant surgery methods by superimposition of DICOM files and 3D data sets of the jaws. In order to design a 3D-printed template with the aid of a fully digital workflow; the third molar was conserved in PRGF during the surgical procedure and the tooth socket was prepared with a template and the help of a 3D-printed donor tooth copy in order to prevent iatrogenic damage to the donor tooth. This template and replica were manufactured using 3D-printing techniques. The transplanted tooth was placed in infra-occlusion and fixed with a suture splint and root canal therapy was performed 15 days later. The intervention was be accomplished by performing preplanned virtual transplantations with guided osteotomies to ensure accurate donor tooth placement in the new recipient site. The 24 months follow-up showed physiological clinical and radiologic results compatible with healing periradicular tissues. CONCLUSIONS: This approach enables the planning and production of a 3D printed surgical template using the latest diagnostic methods and techniques of guided implant surgery. These accurate virtually predesigned surgical templates and printed analogues of the donor tooth could facilitate autotransplantation, ensuring an atraumatic surgical protocol.

RESUMO

La osteomielitis focal esclerosante es un cuadro de poca frecuencia ante el cual no existen demasiadas opciones terapéuticas, al margen del tratamiento de conductos del diente afectado. En caso de no encontrarse el diente vital, los tratamientos se reducen y, respecto del hueso afectado, no existen evidencias científicas sobre la colocación de implantes. Presentamos un caso clínico en el que se maneja este cuadro eliminando el hueso y regenerándolo con PRGF-Endoret®, para colocar posteriormente un implante dental. (AU)


Focal sclerosing osteomyelitis is a rare condition with few therapeutic options other than root canal treatment of the affected tooth. If the tooth is not vital, the treatments are reduced, and there is little scientific evidence of the benefits of the placement of implants in the affected bone. We present a clinical case in which this condition is managed by removing the affected bone, regenerating it with PRGF-Endoret® and subsequently placing a dental implant in the treated area. (AU)

RESUMO

BACKGROUND: To assess if photobiostimulation (PBS) alleviates pain intensity/duration and swelling after implant surgery. MATERIAL AND METHODS: Sixty subjects (27 male and 33 female, with a mean age of 47,13 8.05 years) were included and randomly assigned to experimental group (implant surgery and photobiostimulation), placebo group (implant surgery and simulated photobiostimulation) and control group (implant surgery only). INCLUSION CRITERIA: subjects older than 20 years, with a healthy oral mucosa and requiring implant surgery. EXCLUSION CRITERIA: pregnancy, history of implant failure, light sensitivity, metabolic deseases, consumption of antibiotics or corticosteroids in the last two weeks, smokers and alcohol drinkers. Patients reported the pain experienced by using a numeric rating scale (NRS) at 2 hours, 6 hours, 12 hours, 24 hours and from day 2 to 7. Swelling score was assessed by linear measurements and type and number of analgesic drugs within each time-point were recorded on a spreadsheet. Data of pain and amount of swelling were compared among the three groups by using the Kruskal-Wallis H Test and post-hoc comparisons tests. RESULTS: Pain in the experimental group was less compared to controls and placebo group, at each time intervals (p < 0.001) as well as the maximum pain score (experimental group: median = 2, interquartile range 2-3; control group: median = 8, interquartile range 3,75-9; placebo group: median = 8, interquartile range 6,25-9). Swelling was almost insignificant in the experimental group (maximum value = 1, interquartile range 0-2,75, at 24 hours) compared with control (maximum value = 6, interquartile range 5-8,75, at 24 hours) and placebo (maximum value = 6, interquartile range 5-8, at 24 hours). Subjects in the experimental group assumed less analgesics compared to both controls and placebo groups. CONCLUSIONS: Photobiostimulation is an effective method to reduce pain intensity/duration and swelling after implant surgery

RESUMO

OBJETIVOS: Describir la prevalencia y localización de la anastomosis intraósea (AIO) del conducto alveolar superior posterior (CASP) con el conducto alveolar superior anterior (CASA) en pacientes portadores de fisura labiopalatina, comparando el lado afectado por la fisura labiopalatina de tipo transforamen incisivo unilateral (FLP) con el contralateral no portador de fisura labiopalatina (NF). MATERIAL y MÉTODO: Fueron evaluadas 1500 tomografías computadorizadas de haz cónico (TCHC) y de acuerdo con criterios de inclusión, 95 TCHC fueron seleccionadas para análisis (52 hombres, 43 mujeres, edad media 27 años). La muestra fue conformada por: 1) pacientes con FLP en el lado derecho y NF en el lado izquierdo; y 2) pacientes con FLP en el lado izquierdo y NF en el lado derecho. El análisis fue dividido en 4 etapas: 1) calibración intra e interexaminador; 2) evaluación de la presencia/ausencia de la AIO del CASP con CASA; 3) localización de la AIO del CASP con CASA, tomando como referencia las caras mesiales de los dientes (17/27), (16/26), (15/5) y (14/24); y 4) comparar la simetría/asimetría de localización comparando el lado portador de FLP con el contralateral NF. RESULTADOS: La prevalencia total de la AIO fue de 67,9 %. La prevalencia de la AIO en el lado portador de FLP fue 71,6 % y en el lado NF fue 64,2 % (Test de Fisher > 0,35). La localización de la AIO en el lado portador de FLP fue más prevalente en las áreas (15/25), (16/26) y en el lado NF fue en el área (14/24) (Test Chi-cuadrado < 0.03). La AIO es asimétrico en el 71,5 % (Test de Fisher < 0.03), cuando se compara el lado FLP con el contralateral NF. CONCLUSIONES: La prevalencia de la AIO fue mayor en el lado portador de FLP (71,6 %) comparado con el lado NF (64,2 %). La localización de AIO en el lado portador de FLP fue dislocado hacia distal a diferencia de su contralateral NF. La AIO fue asimétrica en 71,5 % de los casos. Esta información es relevante en procedimientos quirúrgicos que son realizados en pacientes con fisuras labiopalatinas, que tienen por objetivo corregir las discrepancias maxilomandibulares


OBJECTIVES: The purpose of this study was to examine the prevalence of intraosseous anastomosis (AIO) between the posterior superior alveolar canal (CASP) and the anterior superior alveolar canal (CASA) in patients with cleft lip and palate, comparing the side affected by unilateral incisive trans-forame fissure (FLP) with the contralateral side not affected by fissure (NF). Material and method: A total of 1500 Cone Beam Computed Tomography (TCHC) were evaluated and, according to inclusion criteria, 95 TCHC were selected for analysis (52 men, 43 women, average age 27 years). The sample consisted of 1) patients with FLP on the right side and NF on the left side; and 2) patients with FLP on the left side and NF on the right side. The analysis was divided into 4 steps: 1) Intra and inter-rater calibration; 2) evaluating presence or absence of AIO anastomose between the CASP with CASA; 3) Location of the AIO anastomose between the CASP with CASA, as reference to the mesial aspect of each tooth (17/27), (16/26), (15/25) and (14/24); 4) Evaluated symmetry/asymmetry the localization of AIO, comparing them side with FLP, with the contralateral side NF. RESULTS: The total prevalence of AIO was 67.9 %. The prevalence in FLP side was 71.6 %, and NF side was 64.2 % (Fisher's test > 0.35). The location of the AIO in the FLP side was more than prevalent in the areas of (15/25), (16/26) and on the NF side, it was in the area (14/24) (Chi-square test < 0.03). The AIO was 71.5% (Fisher's test > 0.03) asymmetric comparative of the FLP side with the contralateral NF. CONCLUSIONS: The prevalence of AIO was higher in FLP side (71.6 %) comparing the NF side (64.2 %). The location of AIO, in the FLP side was dislocated distally when compared with the contralateral side NF. The AIO was asymmetric in 71.5% of the cases. This information is relevant in surgical procedures that are performed in patients with cleft lip and palate, which aim to correct maxillomandibular discrepancies

RESUMO

OBJECTIVES: A randomized clinical trial was conducted to compare all three known static guided surgery protocols (pilot, partial, and full) with each other and with freehand surgery in terms of accuracy, under the same conditions. MATERIAL AND METHODS: A total of 207 implants of the same brand and type were placed in 101 partially edentulous volunteers in need of implantation in the mandible or maxilla or both. All cases were digitally planned, and the comparison of the planned and actual implant positions was performed using a medical image analysis software with dedicated algorithms. The primary outcome variable was angular deviation (AD, degrees). The secondary outcome variables were coronal global deviation (CGD, mm), apical global deviation (AGD, mm), and voxel overlap (VO, %). RESULTS: AD showed stepwise improvement in significant steps as the amount of guidance increased. The highest mean AD (7.03° ± 3.44) was obtained by freehand surgery and the lowest by fully guided surgery (3.04° ± 1.51). As for the secondary outcome variables, all guided protocols turned out to be significantly superior to freehand surgery, but they were not always significantly different from each other. CONCLUSIONS: As for the comparison that this study sought to perform, it can be said that the static guided approach significantly improves the accuracy of dental implant surgery as compared to freehand surgery. Furthermore, the results suggest that any degree of guidance yields better results than freehand surgery and that increasing the level of guidance increases accuracy.
