“…The whip mix uses the nasion–porion as a reference plane; whereas Hanua articulators mount the cast in relation to the Frankfort horizontal plane, producing more precise angles [ 38 , 39 ]. Due to the substantial differences in the instruments, a slightly modified method for detecting SCGVs is inconsistent, lacks precision, and has lower levels of reproducibility [ 40 , 41 ]. The reasons for the compressed or deformed records include tipped casts due to incorrect cast adaptation, force exerted by the operator on the record, and records whose values have changed depending on the amount of protrusion, overjet, and overbite [ 1 , 41 , 42 ].…”

Additionally, because set inter-condylar distance and straight condylar pathway, the semi-adjustable articulators are unable to properly reconstruct the condylar movements [ 41 ].…”

“…Similar outcomes were found in the individual studies that were excluded from the review. For instance, in the study by Kumar et al [ 50 ], condylar guidance values obtained from CBCT measurements were 5°–6° higher than those from protrusive occlusal records, while values obtained from clinical methods were attested in three studies mentioned in the literature [ 40 , 41 , 51 ]. The major benefit of CBCT over intraoral, panoramic, and cephalometric is the production of distinctive images that show 3D features.…”

The condylar guidance value (CGV) measurement constitutes an important part of a holistic prosthodontic treatment plan, with horizontal CGVs (HCGVs) and lateral CGVs (LCGVs) being two of the most prominently recognized. This systematic review aimed at evaluating the efficacy of two different types of CGV measurement protocols—articulators (both arcon and non-arcon) and panoramic radiographs. Additionally, it attempts to determine which of the mentioned methods performs better across several parameters. Several important web databases were searched using search terms derived from medical subject headings (MeSH), using keywords linked to “Arcon articulator”, “Condylar guidance angle”, “non-arcon articulator”, “Panoramic x-ray” and “Radiographic examination”, which constituted the first step in the study selection strategy. After completion, the search strategy which initially turned up to 831 papers, eventually ended up with 13 studies. The review and subsequent meta-analysis revealed that panoramic radiographs had noticeably greater efficacy in terms of the CGVs as compared to the articulators in the majority of the studies. Within the articulators, the arcon types recorded slightly higher CGVs than the non-arcon variety owing to the precision of jaw movement simulation in the former. However, further studies are required to validate these findings and establish more precise guidelines for the use of CGV measurement protocols in prosthodontic practice.

“…Finalmente, es conveniente contrastar las medidas obtenidas del AGCS en la toma radiográfica lateral estricta con otros métodos de medición, como el trazador pantográfico Cadiax® Compact, que sirve para el registro computarizado del AGCS utilizado por Naqash et al . en su estudio 11 .…”

“…Naqash et al . 11 , en 2020, utilizaron los siguientes métodos: clínico, radiográfico y pantográfico para determinar el AGCS en una muestra de 23 pacientes dentados de 18 a 30 años, y concluyeron que existe una fuerte correlación entre los tres métodos para hallar el AGCS. Das et al .…”

Objetivo: Comparar el ángulo de la guía condílea sagital obtenida del registro radiográfico y clínico en pacientes dentados. Materiales y métodos: La muestra estuvo conformada por un grupo único de estudio de 32 pacientes, en el que se evaluó la radiografía lateral estricta y los registros posicionales: en relación céntrica, registro protrusivo a 5 mm en lateralidad derecha y registro protrusivo a 5 mm en lateralidad izquierda. Con el registro posicional del arco facial se articuló el modelo superior, con el registro posicional en relación céntrica se articuló el modelo inferior, con los registros laterales protrusivos de los lados derecho e izquierdo se obtuvo la medida del ángulo de la guía condílea sagital para la programación del articulador semiajustable. El plan estadístico en la presente investigación utilizó el programa SPSS versión 24, la normalidad fue evaluada usando el test de Shapiro-Wilk, también se realizaron las pruebas de T de Student y correlación de Pearson. Resultados: Se determinó estadísticamente que el género y la edad influyen en la medida del ángulo de la guía condílea sagital. El método radiográfico presentó un ángulo de guía condílea de 35,69 ±5,18 y con el método clínico fue 35,69 ± 5,16 (p > 0,05). La prueba de correlación de Pearson sí mostró una correlación importante entre ambos métodos r = 0,948, p < 0,001. Conclusiones: Existe alta correlación en las medidas obtenidas del ángulo de la guía condílea sagital con los registros radiográficos y clínicos; esta concordancia permitiría reemplazar un método por el otro.
