“…Although panoramic radiography has been used as a reference method in different studies, various investigations agree with the present results showing the lack of an association between low axial and/or peripheral BMD and mandibular bone rarefaction [11,12,[17][18][19][20][21][22][23][24][25][26].…”

“…Analysis of the morphology of the mandibular cortex on panoramic radiographs according to the classification of Klemetti and Kolmakow [12] showed a normal cortex in 5 patients with osteoporosis and in 11 control subjects, and a moderately or severely eroded cortex in 14 patients with osteoporosis and in 9 controls. There was no significant difference between the osteoporosis and control groups when comparing subjects with a normal cortex to those with severe or moderate erosion of the cortex (χ 2 ; P=0.1053) ( Table 2).…”

“…Mandibular cortical shape on dental panoramic radiographs was determined by bilateral observation of the mandible distally from the mental foramen and was classified into three groups according the criteria of Klemetti et al [11] and Klemetti and Kolmakow [12] as follows: (1) normal cortex: the endosteal margin of the cortex is even and sharp on both sides, (2) mildly to moderately eroded cortex: the endosteal margin shows semilunar defects (lacunar resorption) or appears to form endosteal cortical residues, (3) severely eroded cortex: the cortical layer forms heavy endosteal cortical residues and is clearly porous.…”

Introduction: In view of the increase in the life expectancy of humans and in edentulism of the population above 50 years of age, in which the prevalence of osteoporosis is also higher, it is fundamental to better understand the effects of systemic bone mass loss on the healing process of dental implants and to determine the quality of the bone that surrounds them. The objective of the present study was to compare systemic osteoporosis (axial and femoral) and parameters of mandibular bone quality, and to evaluate osseointegration in postmenopausal women receiving dental implants. Methods: The sample consisted of 39 women aged 48-70 years, 19 with a densitometric diagnosis of osteoporosis in the lumbar spine and femoral neck and 20 controls with a normal densitometric diagnosis. Bone mineral density was measured in the patients and controls by dual-energy X-ray absorptiometry. Eighty-two osseointegrated dental implants were placed in the mandible, 39 of them in the osteoporosis group and 43 in the control group. Mandibular bone quality was evaluated by classifying mandibular inferior cortical and trabecular bone on panoramic radiographs and by histomorphometric analysis of a mandibular bone biopsy. Osseointegration was analyzed after 9 months. Results: No significant difference was observed between patients with osteoporosis and controls when comparing individuals with a normal cortex and those with a severely or moderately eroded cortex determined on panoramic radiographs, although patients with MEC/SEC had lower femoral neck BMD than those with NC (0.688 ± 0.17 vs. 0.814 ± 0.144 g/cm 2 , P<0.012). Histomorphometric analysis also revealed no difference in the parameters of bone formation or resorption between the two groups. Implant failure was observed in only one case. Conclusion: We conclude that there is an association between low femoral neck BMD and poor mandibular bone quality as assessed by panoramic radiography. The loss of one implant (1.2%) is compatible with the literature and cannot be attributed to systemic osteoporosis.

Morphology of the mandibular cortex on panoramic radiographs as an indicator of bone quality.

Abstract: The use of an ordinal classification of the mandibular cortex on panoramic radiographs may be helpful for general dental practitioners in the assessment of the local quality of the cortical bone.
