bonding

Etymology: ME, band, to bind

1 (in dentistry) a technique of joining orthodontic brackets or other attachments directly to the enamel surface of a tooth, using orthodontic adhesives.

2 the reciprocal attachment process that occurs between an infant and the parents, especially the mother. Bonding is significant in the formation of affectionate ties that later influence both the physical and psychologic development of the child. It is usually initiated immediately after birth by placing the nude infant on the mother's abdomen so that both the parents and the child can see and touch one another and begin to interact. The newborn is in an alert, reactive state for about 30 minutes to 1 hour after birth and displays such behaviors as crying, sucking, clinging, grasping, and following with the eyes, which in turn stimulate the expression of parenting instincts. By about the second to third week of the infant's life, a definite, reciprocal pattern of interacting behavior that involves an attention-nonattention cycle occurs during each encounter of parents and child. At the peak of the attention phase, the infant reaches out toward the parent and is very attentive. This peak is followed in a short time by deceleration of excitement in the infant and a turning away from the parent. This nonattentive phase prevents the infant from being overwhelmed by excessive stimuli, and no visual or verbal attempt will regain the infant's attention. Recognizing that the nonattention phase does not represent rejection helps the mother and father develop competence in parenting. Assessment of the attachment process is an important nursing function and requires skillful observation and interviewing. The nurse observes the mother's reactions, especially while feeding, bathing, and comforting her infant, for potential signs of inadequate or delayed mothering. Among the most important actions for bonding are eye contact in the en face position and embracing of the infant close to the body. Many variables determine the development of bonding and parenting, including the parents' fantasies about the child, the conditions surrounding the pregnancy, the arrangements that have been made concerning changes in life-style with the addition of a dependent family member, and the type of parenting the mother and father received as children. Bonding is also seen in adoptive situations and is not limited to the newborn period. Although bonding is considered primarily an emotional response, it is hypothesized that some biochemical and hormonal interaction in the mother may stimulate the response; results of studies testing this hypothesis are inconclusive. Also called maternal-child attachment. See also maternal deprivation syndrome, maternal-infant bonding.

bonding [bond´ing]

1. joining together securely with an adhesive substance.

2. the development of a close emotional tie to a mate or to a newborn; called also claiming and binding-in. It is thought that optimal bonding of the parents to a newborn requires a period of close contact in the first few hours after birth. The mother initiates bonding when she caresses her infant and exhibits certain behaviors typical of a mother tending her child. The infant's responses to this, such as body and eye movements, are a necessary part of the process. The length of time necessary for bonding depends on the health of the infant and mother, as well as on circumstances surrounding labor and delivery. The presence of the father during the birth increases his bonding to the infant.

bonding, direct,

n an individual placement of attachments on the teeth at the time of adhesion.

bonding, enamel,

v the process of adhering a coating, or liquid enamel, to the surface of a tooth. It is utilized for various aesthetic and functional reasons, including the repair of caries and chipped or cracked surfaces or to cover exposed roots due to gingival recession. See also sealant, enamel.

bonding, indirect,

n the positioning of attachments on a dental cast and transfer of them to the teeth en masse for adhesion by means of a molded matrix bone.
