ABSTRACT Objective:  To evaluate the capability of both cervical vertebral maturation (CVM) stages 3 and 4 (CS3-4 interval) and the peak in standing height to identify the mandibular growth spurt throughout diagnostic reliability analysis. Materials and Methods:  A previous longitudinal data set derived from 24 untreated growing subjects (15 females and nine males,) detailed elsewhere were reanalyzed. Mandibular growth was defined as annual increments in Condylion (Co)–Gnathion (Gn) (total mandibular length) and Co–Gonion Intersection (Goi) (ramus height) and their arithmetic mean (mean mandibular growth [mMG]). Subsequently, individual annual increments in standing height, Co-Gn, Co-Goi, and mMG were arranged according to annual age intervals, with the first and last intervals defined as 7–8 years and 15–16 years, respectively. An analysis was performed to establish the diagnostic reliability of the CS3-4 interval or the peak in standing height in the identification of the maximum individual increments of each Co-Gn, Co-Goi, and mMG measurement at each annual age interval. Results:  CS3-4 and standing height peak show similar but variable accuracy across annual age intervals, registering values between 0.61 (standing height peak, Co-Gn) and 0.95 (standing height peak and CS3-4, mMG). Generally, satisfactory diagnostic reliability was seen when the mandibular growth spurt was identified on the basis of the Co-Goi and mMG increments. Conclusions:  Both CVM interval CS3-4 and peak in standing height may be used in routine clinical practice to enhance efficiency of treatments requiring identification of the mandibular growth spurt.

Pendahuluan: Beberapa tahun terakhir, hubungan antara cervical vertebral maturation (CVM) dengan pertumbuhan mandibula yang dinilai melalui panjang mandibula mendapat perhatian. Pemahaman mengenai pertumbuhan dan perkembangan kraniofasial pasien sangat penting dalam membantu menegakkan diagnosis, merencanakan perawatan, dan keberhasilan perawatan ortodonti. Waktu perawatan ortodonti berhubungan dengan keparahan dan tipe maloklusi yang dikaitkan dengan tingkat maturitas pasien. Tujuan penelitian ini adalah untuk menganalisis hubungan tingkat maturitas vertebra servikalis dengan panjang mandibula. Metode: Jenis penelitian analitik dengan rancangan cross sectional. Sampel penelitian menggunakan 100 foto sefalogram lateral pasien usia 8-18 tahun dengan Klas I skeletal. Kualitas foto sefalogram lateral baik dan berasal dari laboratorium yang sama. Pengumpulan data dilakukan dengan menganalisis tingkat maturitas vertebra servikalis dan mengukur panjang mandibula pada sefalogram lateral. Uji statistik yang digunakan ANOVA dan Kruskal-Wallis, analisis korelasi menggunakan Pearson. Hasil: Terdapat perbedaan yang bermakna pada panjang mandibula laki-laki dan perempuan, dengan nilai p=0,009. Panjang mandibula pada laki-laki lebih besar dibandingkan perempuan. Peningkatan panjang mandibula tertinggi pada laki-laki terjadi dari cervical vertebrae maturation stages (CVMS) 3 ke CVMS 4 sebesar 8,19±5,79 mm dan pada perempuan terjadi dari CVMS 3 ke CVMS 4 sebesar 6,38±4,51 mm. Hubungan yang paling erat adalah pada tahap CVMS 3 ke CVMS 4 sebesar 0,858 yang bersifat kuat. Simpulan: Terdapat hubungan antara tingkat maturitas vertebra servikalis dengan panjang mandibula, pada setiap tingkat maturitas vertebra servikalis terjadi peningkatan panjang mandibula. Hal ini menunjukkan bahwa pertumbuhan mandibula sejalan dengan maturitas vertebra servikalis.Kata kunci: Maturitas, vertebra servikalis, panjang mandibula. ABSTRACTIntroduction: In recent years, the relationship between cervical vertebral maturation (CVM) and mandibular growth assessed by mandibular length has received attention. Understanding the patient’s craniofacial growth and development is very important in helping make the diagnosis, planning treatment, and the success of orthodontic treatment. The orthodontic treatment timing was related to the severity and type of malocclusion associated with the patient’s maturity level. This study was aimed to analyse the relationship between cervical vertebrae maturity level and mandibular length. Methods: This was an analytic study with a cross-sectional design. The study sample used 100 lateral cephalogram photos of patients aged 8-18 years with skeletal Class I. The quality of the lateral cephalogram images was good and came from the same laboratory. Data collection was carried out by analysing the cervical vertebrae’s maturity level and measuring the mandibular length on the lateral cephalogram. The statistical test used was ANOVA and Kruskal-Wallis, and the correlation analysis used was Pearson. Results: There were significant differences in the male and female mandibular length, with the p-value = 0.009. The mandibular length in male was higher than in the female. The highest increase in the male mandibular length occurred from cervical vertebrae maturation stages (CVMS) 3 to CVMS 4 by 8.19 ± 5.79 mm, and in women occurred from CVMS 3 to CVMS 4 by 6.38 ± 4.51 mm. The closest relationship was at the CVMS 3 to CVMS 4 stage of 0.858, which was categorised as strong. Conclusion: There is a relationship between the maturity level of the cervical vertebrae and the mandibular length. At each maturity level of the cervical vertebrae, there is an increase in the mandibular length. These results suggest that the mandibular growth is in line with the maturity of the cervical vertebrae.Keywords: Maturity, cervical vertebrae, mandibular length.

Abstract Objective: To evaluate mandibular dimensional changes and regional remodeling occurring during five intervals of circumpubertal growth. Materials and Methods: This investigation evaluated a unique sample of subjects in whom tantalum implants were placed into the craniofacial complex during childhood. The sample was obtained from the Mathews and Ware implant study originally conducted at the University of California San Francisco in the 1970s, with longitudinal cephalometric records of 20 subjects (13 female, 7 male) available for evaluation. Cephalograms at six consecutive stages of cervical vertebral maturation (CS1 through CS6) were analyzed. Results: Peak mandibular growth was noted during the interval from CS3 to CS4. Forward rotation of the mandible was due to greater mandibular growth posteriorly than anteriorly. Progressive closure of the condylar-ramus-occlusal (CRO) angle resulted in a forward and upward orientation of the ramus relative to the corpus of the mandible due to increased vertical growth of the condyle. Conclusions: A peak in mandibular growth at puberty was substantiated. Mandibular remodeling and condylar rotation continue to occur after the growth spurt.

The relationship between body height and body weight has been described by using various terms. Notable among them is the body mass index, body surface area, body shape index and body surface index. In clinical setting the first descriptive parameter is the BMI scale, which provides information about whether an individual body weight is proportionate to the body height. Since the development of BMI, two other body parameters have been developed in an attempt to determine the relationship between body height and weight. These are the body surface area (BSA) and body surface index (BSI). Generally, these body parameters are described as clinical health indicators that described how healthy an individual body response to the other internal organs. The aim of the study is to discuss the use of BSI as a better clinical health indicator for preclinical assessment of body-organ/tissue relationship. Hence organ health condition as against other body composition. In addition the study is `also to determine the best body parameter the best predict other parameters for clinical application. The model parameters are presented as; modeled height and weight; modelled BSI and BSA, BSI and BMI and modeled BSA and BMI. The models are presented as clinical application software for comfortable working process and designed as GUI and CAD for use in clinical application.
