Comparison of Clinical, Periapical Radiograph, and Cone‐Beam Volume Tomography Measurement Techniques for Assessing Bone Level Changes Following Regenerative Periodontal Therapy

Abstract

Overall, compared to direct surgical measurements, CBVT was significantly more precise and accurate than IRs. If supported by further research, CBVT may obviate surgical reentry as a technique for assessing regenerative therapy outcomes.

Bone density of defects treated with lyophilized amniotic membrane versus collagen membrane: a tomographic and histomorfogenic study in rabbit´s femur

“…A software adapted to Cone Beam Computed Tomography (Sirona, Bensheim, Germany), which is significantly more accurate in its measurements of intraoral radiographs, was used. In a study, Grimard et al 13 compared measurements with digital intraoral and cone beam images (CBCT) to measure 35 internal defects, concluding that CBCT measurements were significantly more accurate than intraoral radiographs, and comparable with direct surgical measurements. This is because the three-dimensional image can obtain a proper orientation in three views and measuring changes occurring after bone grafting procedures (defect filling and resolution) with better accuracy and similarity to direct measurements.…”

Use of cone beam computed tomography in periodontology

“…Bone grafting is commonly used for maxillary sinus lifting and treatment of intra bony defects but evaluation of osseous defect regeneration with conventional radiography can be insufficient due to superimpositions [25,32] . Furthermore, histological evaluation of a sample of the graft is not a preferred method due to its quite invasive procedure.…”

“…CBCT was found to be significantly more accurate than digital intraoral radiographs when direct surgical measurements served as the gold standard for the evaluation of intra-bony defects' regenerative treatment outcomes. CBCT can replace surgical re-entry by providing 3D images and measurements that are almost equivalent to direct surgical measurements [32] . Dimensions of alveolar process should be examined in detail prior to dental implant placement to avoid various complications and evaluation of CBCT images has a major importance in preoperative planning and postoperative localization of dental implants [8,33] (Figure 10).…”

“…There are contradictory results on whether CBCT or conventional radiographs are more efficient in evaluation of periodontal ligament space [6,16] . Assessment of regenerative periodontal therapy and bone grafts' outcomes can be performed accurately and reliably with CBCT imaging [17,32] . In conclusion, CBCT applications provide obvious benefits in periodontology, although it should be used when two-dimensional radiographs are insufficient considering the necessity and the potential radiation hazards of the examination [36] .…”
