Klinik diş hekimliğinin diğer tüm branşlarında olduğu gibi implant uygulamasının en önemli aşaması, teşhis ve planlamadır. İmplantın uzun dönem başarısı için, anatomik, protetik ve mekanik etkenlerin dikkate alınması gerekir. İmplant diş hekimliğinde radyolojik değerlendirmede geleneksel radyografi, tomografi, çalışma modelleri, mukoza kalınlığının ölçülmesi, kemik yoğunluğunun belirlenmesi gibi özel teşhis metotları mevcuttur. Hastada hangi görüntüleme tekniğinin kullanılacağına, hastanın klinik ve özel gereksinimlerine göre karar verilir. Bu çalışmada implant diş hekimliğinde kullanılan radyografik tekniklerin cerrahi ve protetik tedavideki yararları sunulmuştur.

“…For a more precise evaluation of the anatomical structures adjacent to the alveolar process, such as the mandibular canal, nasal cavity and maxillary sinus, this examination modality is strongly recommended (Tyndall, 2000). CBCT consists of several continuous sections that can be viewed in three different planes: axial, coronal and sagittal, eliminating image overlapping and allowing a better evaluation of the extent of the maxillary sinus (Takeshita et al, 2015;Tyndall, 2000;Frederiksen, 2007;Fernandes et al, 1987).…”

Aim: To evaluate the radiographic signs of proximity relationship between maxillary molar roots and maxillary sinus in panoramic radiographs, using CBCT as control. Methods: 81 examinations of patients who had panoramic radiographs and CBCT of the maxillary molars and pre molars region were used. Pathological situations were excluded from this study. Panoramic radiographs and CBCT were evaluated randomly and separately by an experienced dental radiology examiner. 1,055 root apices were evaluated individually. When assessing the relationship between maxillary molar and pre molar apices, and maxillary sinus, the examiner rated the images, both in panoramic radiography and CBCT, according to a scale of 0 to 3, where 0–Without relationship or distant; 1-Root apex projection or overlapping; 2-Maxillary sinus circumventing the tooth root; 3-Interruption of the continuity of maxillary sinus floor. Tabulated data were statistically analyzed using Kappa test and interclass correlation coefficient (ICC) respectively, with a significance level of 5%. A second analysis of the sample was performed after 15 days to analyze reproducibility. Results: Kappa test indicated near perfect reproducibility (Kw=0.973). The highest prevalence ratio, when comparing the classification in panoramic radiographs and CBCT, was for type 1 (52,7%). There was no difference between the type 1 signal and the gold standard observed on CBCT (ρ=0.2152). Conclusion: Panoramic radiography can be used to evaluate the relationship between roots of maxillary molars and premolars with the maxillary sinus. For cases where there is overlapping between apices and maxillary sinus, CBCT remains the indicated exam for better evaluation.

“…Não houve diferença significante na porcentagem da perda óssea entre as diferentes faixas etárias estudadas, no entanto ela foi maior nas superfícies distais dos dentes analisados. O autor observou também, que houve maior incidência de perda óssea nas arcadas superiores do que nas inferiores, havendo diferença entre os grupos dentários.Nenhum estudo foi encontrado na literatura mostrando o uso da tomografia convencional na detecção do nível ósseo alveolar, no entanto, vários trabalhos que foram realizados para planejamento de implantes mostram que a observação das corticais vestibulares e linguais/palatinas somente são possíveis com o uso deste método radiográfico.FERNANDES et a/ 16. (1987) desenvolveram uma técnica tomográfica transversal para observação das estruturas ósseas presentes nas regiões que irão servir de nichos para implantes na mandíbula de 1 O crânios macerados.…”

The periodontology is an area of the dentistry addressed to the treatment of the teeth support structures. The evaluation of the bone and the union tissue have been traditionally noticed with physical methods including the periodontal probing and radiographic exam for bony loss. The objective of this study was to verify to what extent the digital and digitalized radiographies can contribute to overcome the limitations of the traditional radiography (periapical and interproximal) in the measurement determination of the alveolar proximal bony levei. Also, it was intend to accomplish a comparative analysis of the conventional and digitalized radiography appearances of the facial and lingual surfaces of the alveolar bony crests, using cross linear tomography slices of the maxillaries, comparing them with the clinicai measurement. lt was concluded that ali the conventional, digital and digitalized intraoral radiographies, and conventional and digitalized tomographies underestimated the clinicai values of bony levei. The bone levei measurements using intraoral techniques showed larger precision to anterior and posterior teeth's distai surfaces.
