“…Based on linear measurements, without calculating any ratio, Lisson and Scholtes [14] reported reduced upper and lower anterior facial heights, whereas Woodworth et al [17] only found a reduction in the upper anterior facial height. However our findings coincide with most authors observations of a reduced lower facial height only [15,18]. The ratio of posterior to anterior facial height (Jarabak index) did not differ from that of standard controls, thus implying a reduction of the posterior facial height to a similar extent to that of the anterior facial height.…”

“…The same observation was reported by Bauer et al [18]. The Hasund index increased in the total examination group as well as in each of the three subgroups, obviously regardless of whether hypodontia was present in the mandible the maxilla or both jaws.…”

“…Despite these relevant observations, both Yüksel and Ücem [19], who examined the effects of hypodontia dependent on the location of the missing teeth and Øgaard and Krogstad [15] come to the conclusion, that tooth agenesis has little effect on the cranifacial growth pattern. In accordance with this, the recent study of Bauer et al [18], who investigated the general growth pattern according to Segner [20] and Hasund [21], failed to reveal statistically relevant correlation between craniofacial growth pattern and the congenital absence of certain permanent teeth. Alternatively to an unique growth pattern, typical dentofacial structures in persons with hypodontia may be due to a dental and functional compensation [15].…”

“…Øgaard and Krogstad [15] confirmed this, finding a decrease of mandibular plane angle and a reduced anterior facial height in persons with more than 10 congenital missing teeth. The reduction of the anterior facial height is a common report in studies on hypodontia, but wheter it results from a reduction in the upper facial height [5], the lower facial height [18] or both [14] is dicussed controversially. Despite these relevant observations, both Yüksel and Ücem [19], who examined the effects of hypodontia dependent on the location of the missing teeth and Øgaard and Krogstad [15] come to the conclusion, that tooth agenesis has little effect on the cranifacial growth pattern.…”

IntroductionThis study was performed to examine craniofacial structures in persons with hypodontia and to reveal any differences, that may occur, when agenetic teeth are only found in the maxilla, the mandible or in both jaws. The groups consistent of 50 children (33 girls, 17 boys) aged between 9 and 13.5 years were analyzed and assigned to three subgroups. Group 1 = upper jaw hypodontia. Group 2 = lower jaw hypodontia. Group 3 = hypodontia in both jaws.Materials and methodsEleven angular and three index measurements from lateral encephalographs and two linear measurements from dental blaster casts were calculated. All data was statistically analyzed, parameters with p < 5% were investigated for each subgroup respectively.ResultsIn comparison with standards the study group showed bimaxillary retrognathism and a reduction of the lower anterior facial height. Moreover both overbite and overjet significantly increased. Other values laid within the normal ranges. Evaluating results of the subgroups, differences in the means of SNA, SNB and overjet between the groups were observed.Analysis of the mandibular growth pattern revealed, that neither vertical nor horizontal patterns are dominant in hypodontia patients.ConclusionsIn certain dentofacial parameters differences between persons with hypodontia and such with full dentition exist. According to our findings agenetic teeth may have a negative influence on the saggital development of a jaw and the lower face and may be responsible for increased overbites. This should receive attention in orthodontic treatment of hypodontia patients.

“…A very high prevalence of total agenesis of all third molars has also been described. 19 Numerous investigator groups around the world have explored associations between hypodontia and significant alterations in craniofacial morphology in nonsyndromic samples [23][24][25][26][27][28][29][30][31] and craniofacial anomalies such as ectodermal dysplasia 32,33 and Pierre Robin sequence. 34 Whether an association exists between the location of hypodontia and differential alterations in the regional craniofacial morphology in DS is unknown.…”

Objective: To (1) document the prevalence and patterns of hypodontia (permanent tooth agenesis) in Down syndrome (DS) and (2) explore whether maxillary or mandibular hypodontia or simultaneous agenesis of all third molars was associated with differential alterations of the craniofacial morphology. Materials and Methods: Longitudinal panoramic radiographs of 25 white patients with DS (12 male, 13 female; mean age, 15.1 years) treated at The Hospital for Sick Children, Toronto, Ontario, Canada, were evaluated to document hypodontia. Cephalometric measurements of subjects with maxillary or mandibular hypodontia or agenesis of all third molars were compared with those of subjects without hypodontia in these regions using analysis of covariance adjusted for age, gender, and proportion of other missing teeth in the total number of missing teeth. Results: Hypodontia was seen in 92% of the sample when third molars were considered and in 56% when third molars were not considered. Hypodontia was more prevalent and severe in females. The most frequently agenetic teeth were maxillary and mandibular third molars . maxillary lateral incisors . mandibular second premolars . mandibular incisors . maxillary second premolars . maxillary second molars. Simultaneous agenesis of all third molars was seen in 52% of the sample. Maxillary hypodontia was not associated with significant regional craniofacial differences, while mandibular hypodontia was associated with decreased mandibular length and increased ramus:body ratio. Agenesis of all third molars was not associated with significant craniofacial differences. Conclusions: Hypodontia is widely prevalent in DS. The effect of the syndrome appears to be stronger than that of regional hypodontia in differentially altering the craniofacial morphology. (Angle Orthod. 2011;81:260-269.)

These results have implications for several areas of medicine. Joint biological etiology for the agenesis and late maturation of permanent teeth should be considered in developmental research. Orthodontists should be aware of the delay associated with missing second premolars when timing interventions. Forensic age assessment based on tooth development should adjust for missing teeth to avoid underestimating the subject's age.

Craniofacial Growth Patterns in Patients with Congenitally Missing Permanent Teeth*

Abstract: This examination demonstrates no statistically-relevant correlation between craniofacial growth pattern and the congenital absence of certain permanent teeth, although horizontal growth is more frequent (but not significant) in patients with congenitally missing second premolars.
